The geometry of the antenna is derived from an ordinary L-shaped monopole antenna, with the L- shaped radiating patch folded over the ground plane. Compared to ordinary patch antennas, the proposed design uses a smaller ground plane, resulting into a compact antenna. The design is presented for antenna operating over the frequency range from 250-850 MHz. Simulations are performed using the MoM-based Ansoft Designer CAD software. A prototype antenna is fabricated and tested. The prototype antenna has a 10- dB RL bandwidth of 560 MHz ( 117%) and a gain of 4.1dBi at the centre frequency. The gain variation over the band is 1.8 dB. The features of UWB performance combined with compact form factor make it an attractive candidate for handheld portable UWB systems.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121474825","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}

Authors assumed two constraints during the synthesis process: the first is to maintain constant amplitude excitation across the entire array elements and the second one is to vary the inter-element spacing randomly within 0.5λ-1.5λ. A Modified Genetic Algorithm (M- GA) is devised in the present study to find the most optimum arrangement of inter-element spacings corresponding to the radiation pattern with low peak side lobe level (PSLL). To authenticate the efficacy of the proposed technique, an 8×12- element RSPA array is considered as an example and analyzed for its performance. The numerical results obtained through the proposed method are compared with that of an array of equal dimension and with uniform inter-element spacing. The PSLL in both azimuth and elevation planes of synthesized RSPA array is much lower than that uniformly spaced planar antenna (USPA) array.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115847019","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}
