Modern communication technologies have to adapt to be able to meet the ongoing high demand capacity over existing radio channels. This paper proposes a system-level approach based on physical symmetry to improve the electromagnetic performance of a 3-port circulator. A system-level design consisting of two matched circulators connected in a differential configuration is proposed to cancel out residual RF scattering and leakage that causes self-interference in a STAR front-end. The method is validated using a custom designed microwave circulator based on microstrip technology, which forms a building block that operates in the 3–8 GHz band with 20 dB isolation. The proposed RF front-end operates within an extended band of 3–8 GHz while simultaneously exhibiting improvement in isolation by about 10 dB (isolation \u0000<inline-formula><tex-math>$30pm 4$</tex-math></inline-formula>\u0000 dB) between the transmitter and the receiver ports of the STAR system.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"4 2","pages":"253-263"},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10490292","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140345508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For some applications, bandwidth is critical, primarily defining the capability to distinguish targets. Mostly, varying the frequency of an oscillator in the mmWave and THz range is realized by tuning a dc voltage to a variable capacitance. While this is typical for integrated transceivers in silicon-germanium (SiGe) technology, the tunability of a single voltage-controlled oscillator (VCO) limits the bandwidth. This work presents an approach to overcome this limitation by using two simultaneously tuned VCOs combined with a mixer. The oscillators are tuned simultaneously in opposing directions, resulting in an ultra-wideband signal at the mixer's output. The resulting tuning range is the addition of both of the VCOs' respective tuning ranges. The transceiver is realized using the B11HFC SiGe technology, featuring VCOs at center frequencies of 52 GHz and 108 GHz, respectively. The transceivers' output with a center frequency of 111 GHz is continuously tunable over a range of 73.6 GHz (66%). Furthermore, the phase noise contributions from both VCOs along a receiver test are presented.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"4 3","pages":"360-371"},"PeriodicalIF":6.9,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10540599","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141630915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, to achieve the desired (and corrected) consecutive phase differences and relative magnitudes between RF channels, a computer controlled circuit system was developed for dynamic adjustment. The proof-of-concept demonstrator uses a phase sensor, phase shifters (PSs), and variable gain amplifiers, along with other active hardware, to realize a self-calibrating circuit system which achieves the required magnitude and phase for each array element. In addition, measured magnitude and phase imbalances are less than 0.10 dB and 3\u0000<inline-formula><tex-math>$^circ$</tex-math></inline-formula>\u0000, respectively. The computer-controlled feed network is then used to demonstrate that the system can automatically calibrate an active antenna array for various beam steering examples. Also, the S-band feed system can self-calibrate due to any monitored magnitude and phase drifts due to temperature changes and practical component ageing, or, other general channel offsets. This can be considered advantageous and simpler when compared to more established approaches which characterize the coupling between elements or the response of the entire array in the near- or far-field for example.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"4 2","pages":"213-232"},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10479161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140345476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inevitable presence of device motion, however, corrupts the received radar data, reducing target sensing capability and requiring active correction to address the resultant spectral “blurring”. Existing motion compensation techniques utilize computationally intensive post-processing algorithms and/or auxiliary hardware, aspects ill-suited for resource-limited edge devices requiring minimal system latency and complexity. Early works also often consider motion dynamics such as pure single-mode vibration, neglecting additional modes as well as non-harmonic motion content. We resolve both of these limitations by presenting a real-time-compatible, generalized complex motion compensation algorithm capable of correcting multicomponent platform trajectories involving both non-harmonic transients and multimode harmonic vibration. The proposed anchor-based approach achieves average SNR gains of 24.9 dB and 19.7 dB across transient duration and target velocity, respectively, and average multimode harmonic suppressions of 38.9 dB and 29.4 dB across vibration parameters and target velocity, respectively. These results, combined with minimal latency (\u0000<inline-formula><tex-math>$leq ! 240$</tex-math></inline-formula>\u0000 ms), low algorithmic complexity, and the elimination of any additional auxiliary sensors, render the proposed method suitable for deployment in typical edge sensing applications.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"4 3","pages":"440-458"},"PeriodicalIF":6.9,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10538357","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141630913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are challenges which restrict the use of 3D printing for electronic manufacturing. One significant challenge is the characterization of the electromagnetic properties of the 3D printed materials such as their resultant dielectric permittivity. This work reports on the investigation of existing mixture models to establish their suitability for predicting the dielectric permittivity of 3D printed binary materials for the test frequency range of 1 GHz to 10 GHz. The identified models included volume fraction mixture models which considered the material volume concentration of the binary material and shape factor mixture models which consider the geometry and distribution of the mixture constituents. The fused filament fabrication 3D printing process was used for this work. 3D printed samples were produced with varying percentage volume compositions and varying infill patterns. The dielectric permittivity of the samples was investigated using the two-layer stripline measurement method and the measured data compared to the mixture model estimates. The shape factor mixture models were found to not be in good agreement with the measured values of dielectric permittivity. This result was attributed to the relatively small size of the discontinuities within the 3D printed substrate being insufficient to present anisotropy relative to the wavelength of the applied test signals. The volume fraction models were found to be in close agreement for samples with select infill patterns.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"4 2","pages":"277-292"},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10471527","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140345475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
