The proposed array antenna which is designed to work at Ku-band frequency is implemented as a sensing device to transmit and receive emitted electromagnetic waves. A proximity-coupled feeding technique is applied to excite the array antenna due to its advantages in improving bandwidth response and easy to achieve impedance matching condition. The array antenna is composed of eight square patches in a 2×4 array configuration and deployed on two layers of RT/Duroid 5880 dielectric substrate. After realization, the prototype of array antenna is experimentally characterized in an anechoic chamber. The result of measurement demonstrates that the prototype has the radiation characteristics comparable to the simulation. It has the measured reflection coefficient of –34.72 dB at the operating frequency of 14.8 GHz with the –10 dB impedance bandwidth of 980 MHz.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125037752","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 rapid expansion of new applications such as extended reality, telemedicine, and the internet of everything necessitates higher data speeds, lower latency, and more reliability. These needs inspire academics and industries to introduce the sixth generation (6G) to overcome the limitations of 5G and meet the demands of future applications. This article reviews the 6G vision and proposed technologies that expect to be used in the 6G network benefits and challenges. This review’s contribution investigates multiple access techniques, focusing on filter bank multi-carrier. These multiple-access techniques were studied and compared in terms of spectrum efficiency, cyclic prefix, and MIMO compatibility. We found that FBMC is the best candidate for 6G.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121908802","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}
