A W-CDMA receiving system for a 4-element array antenna is developed. The adaptive algorithm and the array antenna configuration are changed according to the requirement of the investigation. The performance of the system including synthesized pattern, adaptive weight and bit-error-rate (BER) characteristics are measured for the performance analysis. Results show that signal-to-interference ratio (SIR) can be greatly improved by 6 to 10 dB compared with the single antenna when BER is equal to 10-3. BER of the single monopole with a reflector is lower than that of the single monopole because the monopole with reflector has a higher gain in the direction of the desired wave. However, the SIR improvement of the monopole array is larger than that of the monopole array with a reflector because the array element gain of the monopole to the direction of the interference is larger. It seems that array elements which have homogeneous radiation pattern and high radiation efficiency are suitable to the adaptive array antennas","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":"41 1","pages":"4573-4576"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74449923","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}

Unfortunately, high impedance (high-Z) surfaces capable of operating at lower frequencies tend to be far more susceptible to fabrication errors because of complex surface patterns. In most cases, standard circuit board manufacturing tolerances are too loose to create such high-Z surfaces to the necessary accuracy. To circumvent these difficulties in fabrication, we propose that adding a small degree of anisotropy to high-Z surfaces can enable compensatory tunability for certain planar antennas located on the surface by simply rotating the antenna. Doing so allows fabrication tolerances to be loosened to those available for large scale, inexpensive fabrication","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":"35 1","pages":"357-360"},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73475992","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}
