The CRLH unit cell is a designed by etching an interdigital capacitor (IDC) slot on the top plane along with a circular complimentary split ring resonator (CSRR) on the ground plane. Due to application of CRLH unit cell, zeroth order resonance (ZOR) is obtained at 1.95 GHz along with the conventional first order resonance mode. Analytical and parametric studies show that the electrical size of the antenna can be effectively reduced by increasing the width of the complimentary split rings. Compared to other SIW-IDC antenna, the present design has a smaller cavity size of 0.13λ0×0.13λ0 at lowest resonant frequency. For n=1 mode resonant frequency, a significantly high gain of 5.97 dBi is obtained at 5.65 GHz.","PeriodicalId":168839,"journal":{"name":"2015 IEEE Applied Electromagnetics Conference (AEMC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114966728","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}

Different shapes of the slots namely circular, elliptical, rectangular and triangular are considered. A comparative performance study based on gain, radiation efficiency and scan range of the antenna for the different shapes is studied over X-band frequency range. Several structures are fabricated. 50 Ω microstrip lines are used to excite the antennas. It is observed that the rectangular shaped slot is the best choice if higher gain, radiation efficiency and wide scan range including the stopband is considered.
