This linear polarized microstrip antenna (LPMA) is miniaturized by bending both opposite sides of the antenna. To achieve the low profile, the L-shaped feeder, compensating the reactive of the antenna, has been designed. The dimensions of the proposed antenna are 200 mm×200 mm×15 mm (0.27λ<sub>0</sub>× 0.27λ<sub>0</sub> ×0.026λ<sub>0</sub>) at the center frequency 417 MHz). The antenna has been successfully simulated, fabricated and measured. Experimental results show that the proposed antenna exhibits a good impedance bandwidth of 7 MHz (414 MHz-421 MHz) for VSWR <; 2. The simulation and measured results show a good agreement with each other.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"65 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80183969","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 proposed FSS consists of an array of three-layer printed circuit boards and a number of inserted metallic rods and plates. Under a linearly polarized incident wave with its electric field perpendicular to the printed circuit boards, two propagation paths with four resonators are constructed, providing dual-band performance. Furthermore, the two operating passbands are determined by resonators in the two propagation paths, respectively, which can be designed independently. In order to verify our concept, a design example is given and its simulated results show that the proposed FSS exhibits stable dual-band performance with large band spacing under a large variation of incident angle.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"51 2 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83401145","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}
