Traditionally, power-hungry and bulky motors are used to mechanically scan the antenna beam. At lower-frequencies, phased array antennas are most commonly used where low-loss phase shifters are used with the array elements to accomplish beam steering. However, development of similar phased array antennas at submillimeter-waves has been challenging. Recently, we have developed a low-loss microelectromechanical systems (MEMS) based phased shifter in the 500-750 GHz band. In this work, we present a submillimeter-wave phased array antenna system with a cavity-backed double slot antenna architecture using the MEMS-based phase shifters. To demonstrate the concept, we developed two arrays: first one is a 8$times$1 linear antenna array with a fixed waveguide feeding network that achieved ±20°. beam scanning, 18 dB directivity, and less than 1 dB scan loss over the design frequency of 500.570 GHz. The second one is a 4 $times$ 1 linear antenna array with integrated MEMS-based phase shifters on each array element, achieving 15 dB directivity and capable of dynamic beam scanning over a range of ±9° All the plots presented are simulated results since the parts are currently being fabricated. We hope to have access to our assembly and measurement facilities over the next few months and present measured performances at the conference.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129486013","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}

It consists of two closely located rectangular microstrip patch antennas, and these radiating patches give radiation bidirectionally. The isolation between the interports of the Full-Duplex antenna is obtained by using a technique called frequency space filtering and two bowtie-shaped defected ground structure (DGS) based bandpass filters (BPFs) in the ground plane beneath the microstrip feed lines from the transmitting and receiving ports of the antenna. The duplex antenna attains the isolation of $21mathrm{~dB}$ at the transmitting frequency $f_{t}=1.9mathrm{GHz}$ and $34mathrm{~dB}$ at the receiving frequency $f_{r}=2.78mathrm{GHz}$ and transmit-receive frequency spacing frequency $f_{r}=2.78$ GHz and transmit-receive frequency spacing ratio of $r=0.37$. The proposed antenna can operate well at different frequency bands, particularly between 2 and 3GHz by varying the dimensions of the DGS BPF because its resonance frequency depends on scaling the size of the structure. Furthermore, the incorporated BPFs have a reasonable degree of selectivity and sharp frequency cut-off characteristics.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129035944","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}

To reduce the losses further, the concept of on-antenna power combining is explored and one single element dual port microstrip loop antenna having peak gain of more than 5 dBi is designed at 24GHz. A peak efficiency of 66% is achieved at 19dBm input power for the combined rectenna at 24GHz.
