We develop a novel approach for calculating these estimates using a combination of Delaunay triangulations and modified Gaussian ray bundles. This method allows for field intensity estimates at single-point locations anywhere on the surface of the Earth as well as global intensity over an area of regard. The scope of this paper is to give a general outline of this novel approach.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"1998 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131186715","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 gain was enhanced by the subsequent deployment of multiple radiator elements to fabricate a four-element vertically array antenna on an elongated double-cornered reflector. The simulated and measured |S11|<;-10dB of the array antenna respectively covered the 410-991MHz (82.9%) and 415-886MHz (72.4%) frequency ranges. The proposed array antenna radiates unidirectionally across the DTV frequency band with a measured front-to-back ratio and cross polarization <;20dB and >-23dB, respectively. The simulated and measured gains of the array antenna were 12.8-16.4dBi and 11.3-15.8dBi along the 470-862MHz frequency range. This proposed array antenna is thus suitable for DTV broadcasting transmission.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127240232","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 performance was evaluated by: (1) the similarity of dispersion characteristics such as delay spread (DS) and angular spread (AS), (2) computational complexity by comparing computation time. Our results showed that the performance of SAGE and that of BBF are similar. In terms of computational complexity, it could save 98% computation time by BBF instead of SAGE. Compared with our prior work, this paper analyzed with additional measurement data collected in indoor and outdoor environments, which improved the statistical stability of dispersion parameters.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121631430","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}

One solution to cope with the bad condition is to apply a high spec antenna, however, it is difficult to change antenna specification because in most cases it should comply with system standards. Another possible way is to apply reflectarray which can change radiation direction from antenna, but it is also difficult to install the reflectarray close to one-wavelength size antenna, such as dipole antenna. To address the issue, we have studied the control method to direct maximum radiation beam to desired direction using meta-surface whose elements consist of mushroom like structure without via-hole.","PeriodicalId":143796,"journal":{"name":"2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128994472","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}
