The performance of voice and data will be degraded during wave propagation. This is called propagation fading. The propagation fading will decrease the signal to noise ratio. For smaller signal to noise ratio, the performances of communication range, BER (bit error rate), and data throughput rate will also be degraded. In order to overcome these serious effects of propagation fading, various kinds of reconfigurable antennas are developed for SDR (software defined radio) communication systems. By reconfiguring the existing antenna hardware to change the performance of antenna, the antenna will be more powerful for the application in SDR communication system. The reconfigurable antennas are one of the important parts in SDR communication system. By minor adjusting the reconfigurable antenna, the communication range, lower BER, and higher data throughput rate can be highly improved.","PeriodicalId":119627,"journal":{"name":"2013 IEEE International Workshop on Electromagnetics, Applications and Student Innovation Competition","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126032801","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}

By adopting a coaxial probe which acts as the monopole and printed spoke-like metal strips fabricated on two substrates which act as the loop, the omni-directional circularly polarized (CP) wave can be generated in the azimuthal plane. To make the antenna polarization reconfigurable, 48 PIN diodes are placed on the two substrates to alter the current direction of the loop. An additional DC bias network is used to bias the diodes. The polarization status can be switched between RHCP and LHCP. The measured -10 dB impedance bandwidth is 25% and 26% and the average axial ratio (AR) is 2.33 dB and 2.45 dB for RHCP and LHCP in the azimuthal plane.","PeriodicalId":119627,"journal":{"name":"2013 IEEE International Workshop on Electromagnetics, Applications and Student Innovation Competition","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121415529","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}
