The key challenge to FD is self-interference (SI): a node’s transmitting signal generates significant interference to its own receiver. Recent works have proposed several techniques to reduce SI and enable FD but they are primarily specific to sub-6 GHz frequency bands. In this paper, we focus on mmWave frequencies and propose to design the antennas in a way that they reduce SI. In particular, we design a novel electromagnetic band gap (EBG) architecture and integrate it with the antenna array to reduce SI. Extensive simulations show that the proposed design reduces SI by more than 60 dB over 100 MHz of isolation bandwidth at 28 GHz frequency. We also show that the design has minimal impact on the antenna array gain, maintains the gain over large bandwidth, and has a return loss similar to a design with no EBG.","PeriodicalId":401066,"journal":{"name":"2021 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124995926","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 paper proposes a wireless device RFF identification scheme, which relies on the non-linear memory effect resulting from the concatenation of two matched root-raised cosine (RRC) filters with a non-linear power amplifier (PA) inserted in-between. This unique feature can be extracted from the distorted constellation diagrams, which is processed into density trace figure. Classification algorithm based on image recognition method is developed to exploit the non-linear memory effect from the density trace figure. Simulation setup is carefully designed, and the results validated the effectiveness of our proposed RFF feature classification approach. In the range of SNR 1 dB to 25 dB, the overall identification accuracy rate exceeds 99%.","PeriodicalId":401066,"journal":{"name":"2021 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116680535","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}

A simple design approach and formulas are presented. This is followed by EM simulation results and lab measurement results for a set of prototypes operating over a range of frequencies relevant to millimeter wave (mmWave) systems. The simulation results based on the calculated array dimensions show good characteristics. The measured gains and radiation patterns agree well with the simulation results. Overall, the usefulness of the design strategy for application to antennas in the mmWave band is confirmed.","PeriodicalId":401066,"journal":{"name":"2021 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"1122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121840216","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}

Element-wise reconfigurable impedance tuners can be used to optimally match the power amplifier device; however, the impedance matching can also affect the array pattern. In this paper, the effects of element-wise impedance tuning on the transmitted power and on the array pattern are studied, and an approach is recommended for the element-wise implementation of impedance tuners. Examples of impact on array pattern and transmitted power are given using simulation of a designed switched-stub impedance tuner. As a result of these experiments, guidelines are developed for the creation of real-time circuit optimization techniques in the array elements.","PeriodicalId":401066,"journal":{"name":"2021 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126970840","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}
