The design was initiated from a tapered microstrip to substrate integrated waveguide (SIW) transition and stubs are used at the feeding to improve impedance matching. Additionally, the CSIW implemented in the transition is meant for further size reduction, improved bandwidth, and reduced insertion loss. The measured fractional impedance bandwidth of 50 % (12-18 GHz) below -15 dB (simulated: -18 dB) has been achieved of the proposed transition. An insertion loss below 3 dB is obtained. The measured results are in agreement with the simulation results.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352591","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}

The proposed method is built by taking into account the complexity issue because the complexity of the model increases with the increase in the number of paths. For proof of concept, the method is implemented for 2X2 MIMO. With the simulation results, it has been established that complexity of the proposed method is much reduced for 4X4, 8X8 and 16X16 MIMO scenarios than the established multi-input digital predistortion solutions.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115670953","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}

This supported the derivation of an equation for the estimation of such errors with dielectric measurement for an unknown material compared to the S11 value with a reference material in contact with a coaxial probe. Frequencies of 0.50, 1.5 and 3.0 GHz were applied for calculation. Specifically: 1. The dielectric constants of various liquids were initially set on the basis of reference and unknown materials previously examined by the author. 2. S11 values were calculated via the MoM (method of moments) approach based on transverse EM analysis using a model with the assumption of actual measurement using a coaxial probe and various liquids in contact with the jig. 3. The dielectric constant and S11 values were substituted into the equation used to estimate the dielectric properties of an unknown material as compared with a reference material. 4. The dielectric constant difference between values estimated using this equation and the values set for S11 computation was calculated. 5. Complex permittivity errors caused by differences in the physical structure of the equivalent circuit in derivation of the estimation equation were determined under various conditions of frequency and unknown materials. The results showed that the complex permittivity of methanol estimated using the equation with pure water as the reference material, by way of example, became smaller than the true value as the frequency increased. The estimation error was also found to increase with frequency, showing values between 4.012 and 11.456% at 3.0 GHz.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128161632","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}

The sensor is designed by etching a complementary split ring resonator (CSRR) at the center of the SIW waveguide E-plane. The designed resonant sensor structure facilitates the testing of samples without a need for fitting them precisely inside the SIW cavity. Moreover, the presence of maximum electric field at the center of E-plane helps to achieve the relatively higher perturbation and hence higher sensitivity. The Q-factor (107) and sensitivity (12.3%) of the designed sensor is found to be relatively higher than the microstrip counterpart (8.9%, 54). The developed sensor is experimentally tested for the number of standard test specimens, and the results are in good agreement with their reference values.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114516568","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}

The condition of zero reflections is not realizable through the traveling wave scattering matrix theory given the requirement for the reference impedance to be defined as a real value and that the power transfer through a network is not taken into account. In this work, the application of power scattering matrix theory pertaining to signal integrity is presented. The first application of interpreting the frequency-dependent impedance characteristics looking into the network port presents an alternative means of interpreting the impedance characteristics without having to do an Inverse Fast Fourier Transform based Time Domain Reflectometry. The second application of calculating the noise in the insertion loss due to reflections coming from the channel termination presents a figure of merit for system optimization. This work is an attempt to present a methodology to characterize the frequency domain impedance characteristics looking into a network port and noise in the insertion loss due to reflections coming from the channel termination through the application of the power wave scattering matrix.
