It consists of a corner perturbed slot and two asymmetric strips oriented diagonally with the slot. The slot antenna is excited by $50Omega$ microstrip line. The proposed antenna resonates at 2.7 GHz and 3.2 GHz. Two orthogonal degenerate modes produced by the perturbed slot antenna gives CP in lower band and the combination of slot and strip mode gives CP in upper band. The proposed antenna is fabricated and experimentally verified with axial ratio (AR) bandwidth of 13.27% and 13.31% in lower and upper band respectively. The peak gain of 4.68 dB at lower band and 4.81 dB at upper band is achieved. The simulated and measured results are in well agreement and it is good candidate for WiMax and WLAN applications.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"232 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":"131784814","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 QACSP is found to be effective in increasing the XPD values for the entire operational bandwidth across all elevation planes without significantly affecting the dominant mode of resonance.

In the context of mm wave communication for 5G, conformal arrays with moderate number of elements are likely to be deployed for beam steering to achieve better utilization of resources. Only directive elements such as microstrip patch antennas will be useful here. A fast iterative algorithm was proposed by our group to address this. While digital controls offer easy implementation of such beam steering arrays, these pose an additional challenge in optimization of beam characteristics.
