In this paper, combining the latest development of digital metamaterial and RFID technology, a UHF RFID transmitter with spatial ASK modulation is proposed to reduce the complexity and the cost of radio frequency communication system equipment. The 1-bit digital metamaterial units based on polarization-insensitive Jerusalem cross structure form the 10×10 coding matrix. The proposed UHF RFID transmitter based on digital metamaterial inno-vatively realizes the spatial ASK modulation from −60° to 60° in azimuth plane. Finally, a preliminary communication system is built to test the performance of transmitter. The test result shows that the modulation depth of the spatial UHF RFID transmitter are all above 75%. The transmitter based on spatial ASK modulation provide a potential ability to solve the problem of missing tags in RFID system.","PeriodicalId":260591,"journal":{"name":"2021 IEEE MTT-S International Wireless Symposium (IWS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128338404","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}

However, the existence of potential defects and inaccuracies has restrained its embrace in a broader application range. To date, various nondestructive procedures have been formulated, which were based on lasers, ultrasonic, and cameras, to test the quality of the fabricated component. This research discusses the development of microwave imaging techniques using half-mode substrate-integrated waveguide (HMSIW) to diagnose the presence of exposed and hidden defects in components produced using AM. The presented sensor has low-profile dimensions, making it to be utilized in-situ process monitoring and ex-situ quality testing in the realm of AM. Defects having a diameter higher than 2mm may be identified using the presented sensor.","PeriodicalId":260591,"journal":{"name":"2021 IEEE MTT-S International Wireless Symposium (IWS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125123428","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 region of the load Smith chart leads to optimal output power and drain efficiency (DE) can be accurately identified as critical to amplifier design. The input and output matching networks are designed using a Chebyshev low-pass architecture, and a step-im-pedance converter structure is used to design the output synthesis network.

The conventional Doppler radar system usually employs two separate transmitting (Tx) and receiving (Rx) antennas for improved Tx/Rx isolation. However, it inevitably adds up to the size of the radar system. By leveraging the characteristics of the rat-race coupler, a common-aperture antenna was designed and integrated together with the radar transceiver on a single printed circuit board (PCB), which dramatically reduces the size of the entire radar system. The proposed antenna's Tx/Rx isolation at 5.8 GHz is measured to be higher than 35 dB. Compared with the conventional two separate antennas with similar isolation, the size of the proposed single antenna is reduced by 160% and the entire radar system is reduced in area by 80% with a size of only 10 cmˣ5 cm. Experiments were carried out in the office environment to wirelessly detect human vital signs. It was demonstrated that the proposed portable radar system integrated with a common-aperture single antenna can successfully capture the physiological signals of respiration and heartbeat.","PeriodicalId":260591,"journal":{"name":"2021 IEEE MTT-S International Wireless Symposium (IWS)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125980024","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}
