A microstrip monopole antenna with two electromagnetic band gap (EBG) elements at each side is designed. Subsequently, introducing an additional radiated element at the ground plane of the proposed EBG antenna is also investigated. The proposed antenna is simulated and optimized using CST Microwave studio software. The proposed antenna was also experimentally verified, exhibiting reasonable agreement between the simulation and measurement results. Interestingly, a wider bandwidth and higher gain is attained compared to the antenna without additional radiating element. Owing to its simple structure as well as good performance, the proposed antenna has the potential to be implemented for medical application.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115908601","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 antennas are fabricated with standard 17μm aluminum wires on a programmable semiautomatic ultrasonic wedge bonder to ensure high reproducibility. Two antennas are demonstrated welding the wires on chips fabricated with the back-end of the line of a commercially-available silicon process. The first design is a dipole antenna with central frequency of operation at 160 GHz, 2 dBi of gain and 20 GHz of bandwidth. The second radiating element is a halfloop antenna with dual-band operation centered at 160GHz and 210 GHz, 8 dBi and 6 dBi of gain, and 23GHz and 15 GHz of bandwidth, respectively. The dipole antenna is shaped to radiate laterally and vertically to the wafer surface at 160 GHz, while the loop antenna radiates at 160 GHz horizontally to the wafer surface, and at 210 GHz with an elevation of 45° respect to it. Compared to the state of the art, the demonstrated antennas own the highest gain for bondwire implementations, and the smallest occupation area since they do not require additional metal cavities to operate.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131360146","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}
