The two dimensional SIW horn antenna array does not satisfy the condition of half wavelength distance between the consecutive antenna element, hence the structure has poor gain. To improve the gain of a horn antenna a three dimensional structure is proposed. The combined beam of four antenna element provides the low HPBW radiation pattern. The maximum gain achieved from the structure is 8.8 dB at the desired frequency, whereas the single element SIW horn antenna has a maximum gain of 5.6dB. At 24 GHz, the SIW horn antenna is a good candidate for radar applications. Multiple horn antennas are combined to satisfy the high gain condition of automotive radar applications.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127675959","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 filter performance has been compared with the FBAR filters with simple conventional planar electrodes. To study the effects of fractal geometries on the performance of FBAR filters, the FEM analysis has been carried out using commercially available CoventorWare™ tool. In our analysis, we have observed that the quality factor of FBAR have been significantly enhanced by introducing specific fractal geometries in electrode. And hence, the enhancement of quality factor had led to improvement in the performance of the different filters. The extracted equivalent circuit parameters of FBAR have been used to design and simulate the filters using Agilent ADS commercial software.
