The antenna coupling circuit comprising capacitive gate feeding and inductive loop provides improved matching and reduced losses resulting in enhanced performance of the JLFET terahertz detector.

To avoid interference with other communication bands, stronger blocking of signals in close vicinity of the lower side of the RX passband was required. To meet the stringent specification masks, the implementation of transmission zeros (TZs) is required. Within this design study, the TZs have been realized applying the extracted-zero (EZ) technique by implementing two offline resonators which are directly coupled to the first/last resonator of the filter, respectively. To the best of our knowledge, this is the first time to report the EZ technique for the application with TM-mode DR. Furthermore, the same type of ceramic rod was applied for the design of TX, RX, and EZ resonators by suitable dimensioning of their enclosure. The design is discussed and measurement performance of a filter panel prototype is presented.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132696435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An improvement was presented in recent publications [2], [3], [4], showing that it is possible to produce in-line bandpass designs with a transmission zero near the passband, using the same physical resonator structure as employed in the bandpass portion. This has been accomplished using shunt resonators weakly coupled (using a virtual inductive coupling) to the first and/or last bandpass resonator, resulting in a configuration that locates the zero near a passband edge, with the concomitant pole located far from the passband. Both the original and the improved circuits have thus been called “Extracted Zero”. Use of the same physical resonator structure simplifies the physical implementation. In this paper, the “Double Extracted Zero” is introduced. Similar in physical structure to the single zero in [1], the double zero is used to provide additional depth or width to the desired zero frequency region, and can be located at either or both ends of a given passband.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124229071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposed system, the reader consists of a transmission line with a gap and the tag consists of a chain of line (strip) resonators. By moving the tag on top of the reader with a small airgap between them, significant transmission in the reader occurs when the line resonator lies on top of the transmission line´s gap, provided the feeding signal is tuned to the frequency of that resonator. The tag is designed by considering four different lengths for the strip resonators, corresponding to four different frequencies, which can be found in the reader´s output according to the length of the line resonator on top of the reader in every time sequence. Therefore, in every time sequence four different states (two bits) can be coded. As a result, the number of bits per length of the tag in this system is twice the number of bits in the tags based on the absence/presence of functional inclusions. According to the explanations above, the reader, which consists of a transmission line with a gap, is fed with four different harmonic signals with frequencies equal to the resonance frequencies of the strip resonators. In this paper, the results related to a tag including four line resonators are provided as a first proof-of-concept demonstrator.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127679242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, a calibration concept derived from vector network analyzer (VNA) measurements is used to calibrate the FMCW radar’s raw IF signal and to measure the reflection coefficient of a material at a much lower cost than the VNA. Second, the measured reflection coefficient is fitted to a complex-valued convolutional neural network (CNN) to determine the dielectric constant, loss tangent and thickness of the material. K-means clustering is proposed to reduce the complexity of the CNN by significantly reducing the number of classes.
