Systematic approach for design of single element antenna followed by performance analysis over curved surfaces has been reported. After achieving the desired performance over the required band for both planar and conformal cases, studies on array analysis has been performed. The maximum realized gain of the single antenna shows a minimum of 8 dBi from 15 GHz to 34GHz. The gain has been significantly increased through array approach. The paper also reports the axial ratio analysis towards study of polarization effect. The analysis shows that, the proposed antenna array is suitable for wireless systems that can be used in aerospace platform.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"34 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":"121458440","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}

For this purpose, position randomness is introduced in a supercell, which transforms a periodic metamaterial structure into a random metamaterial structure, where the constituent resonators are interacting with each other. It is demonstrated that the disorder can be used to enhance the absorption bandwidth. This enhancement is obtained due to the coupling among the nearby resonators, which results in broadening of collective resonance. The proposed disordered metamaterial absorbers also exhibit polarisation-insensitivity and have wide-band absorption for both normal and oblique incidences, which makes them a promising candidate for a variety of applications.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"11 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":"130190410","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}

Gain enhancement of the proposed pattern reconfigurable quasi angled dipole is achieved in end-fire by minimal loading of the DNG unit cells to improve isolation between the switching states. Two switching states of the antenna is achieved with beams at −24° and +26° and corresponding beamwidths of 38° and 40° with an isolation of more than 10 dB between states.

It is observed that by exciting a 90° CSMA with a feed-probe at two different feed-probe positions, two different modes TM01 and TM21 can be excited within the antenna structure. The resonant frequencies of these two modes are different but both of these modes have broadside radiation patterns in E and H plane. It is also observed that a 90° CSMA resonating at higher order TM01 mode has nearly equivalent radiation characteristics with a circular microstrip antenna resonating at dominant TM11 mode resonating at nearly same frequency. Therefore, the 90° CSMA becomes a suitable alternative to a circular microstrip antenna.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"39 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":"114693988","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}
