Two orthogonal components of the radiated wave with the same magnitude are generated by the combined action of the planar antenna and the rotator. The distance between these two structures can adjust the phase difference between two orthogonal components ranging from -90° to 180° and monotonously changing with the frequency. The simulated results indicate that left-handed circularly-polarized (LHCP), right-handed circularly-polarized (RHCP) and two diagonal linearly-polarized (LP) waves are obtained at four different frequencies. Furthermore, these four states of polarized patterns can be switched by scanning the frequency. The proposed antenna with a fixed structure and a single feeding port can potentially be used in some applications requiring multiple polarization patterns.","PeriodicalId":146561,"journal":{"name":"2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123109309","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}

It will be shown that the microstrip-fed SPAs generally exhibit similar gain and radiation pattern compared to the probe-fed SPA. The SPA fed from side edge behaves a larger cross-polarization radiation in E plane while the one fed from open or shorted edge remains the similar cross-polarization level as the probe-fed one. Besides, it was found that the SPA fed from shorted edge behaves a reduced resonant frequency while the one fed from open edge is opposite and performs smallest gain as well as bandwidth compared to other schemes.","PeriodicalId":146561,"journal":{"name":"2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126112215","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}

Antenna being an important component of automotive radar must have good performance, smaller size, low cost, and easy to fabricate characteristics. Recently, microstrip patch antennas having smaller size and easier to be integrated in vehicles are preferred over reflector and lens antennas. In this paper, corporate feed series microstrip antenna arrays are proposed for the automotive radar applications that work on 77 GHz. To achieve the better performance of the antenna, the width of the patch elements is tapered using Taylor Series. A 5×4 designed antenna array has achieved the gain of 18.7 dBi and bandwidth of 1.507 GHz with sidelobe levels of 16.6 dB.
