According to the desired refractive index distribution of the two lens, the metasurfaces, consisting of sub-wavelength metallic square rings with different sizes are optimally arranged. Due to the planar Bessel lens, a surface cylindrical wave radiated from a point source is converted to an inclined non-diffraction surface wave. The planar Bessel lens is fabricated, and the measurement shows good agreement with the full-wave simulation, which verifies the correctness of the design.","PeriodicalId":301959,"journal":{"name":"2020 IEEE MTT-S International Wireless Symposium (IWS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115040613","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 antenna structure consists of three layers with the square radiating patch on the top, the grounded patch with three embedded slots in the middle and the L-shaped feed at the bottom. The wideband bandwidth can be achieved by properly designing the L-shaped feed and the slots. Moreover, the L-shaped feed is terminated with a circular patch to further enlarge the bandwidth. Compared with traditional aperture-coupled patch antennas, the proposed antenna can avoid the effects from other electronic devices while maintaining a relatively broad bandwidth. The simulated results have shown that the presented antenna has obtained a broadband impedance bandwidth (VSWR $leq 2)$ of about 26% (3.45-4.5 GHz) and the total thickness of the structure is 8.8 mm (around 0.1lambda_{b}$ at the lowest operating frequency). The simulated realized gain varies from 2.5 to 4.7dBi across the operating frequency range.","PeriodicalId":301959,"journal":{"name":"2020 IEEE MTT-S International Wireless Symposium (IWS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131838275","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}

Compared to the conventional waveguide BPFs, the proposed filter is composed of cavities to be arrayed in a stacked manner, instead of the ladder manner. As a result, the whole filter only occupies a half or fourth size of its conventional counterparts, at the expense of increasing its insertion loss from 0.09 to 0.19 dB. Due to the transversal coupling topology, each cavity constituting the filter could be independently realized as a first-order sub-filter, simplifying the synthesis process. Besides, a pair of transmission zero (TZ) is generated at the two sides of passband so as to improve the selectivity of filter. The measured results reasonably support the validity of the proposed filter.","PeriodicalId":301959,"journal":{"name":"2020 IEEE MTT-S International Wireless Symposium (IWS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125227618","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}
