In the proposed work, first a pentagonal patch antenna is designed at centre frequency 5 GHz and simulated using Ansoft HFSS and found that the antenna resonates at three frequency 5 GHz, 10.7 GHz and 14.2 GHz. In the next step a low pass filter cornered around 5 GHz is designed and integrated with a pentagonal patch antenna. Analysis of obtained structure shows only one resonance at 5 GHz with a return loss of around 15 dB hence eliminates two harmonics of 10.7 GHz and 14.2 GHz. Then for rectification purpose, a Schottky diode is characterized at 5 GHz as well as the proposed antenna structure is matched to the optimal complex impedance, consequently the RF-DC conversion efficiency of the rectenna is found to be 54%.","PeriodicalId":286435,"journal":{"name":"2013 International Conference on Microwave and Photonics (ICMAP)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116043856","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 contribution from this set of infinite images has been evaluated using simple closed form expressions for mutual coupling between slot and its image. The convergence of the series is accelerated using Chebyshev-Toeplitz algorithm. The resonant length calculated using this simple and accurate analysis is shown to be in close agreement with measured results and with other theoretical results. The analysis given here can be extended to include other slot aperture distributions with edge condition in the transverse direction or for rounded end slots.
