Each resonator of the antenna is composed of two different dialectic materials stacked together. The aim of dual-segments is to get strong coupling with lower segment of high permittivity and wide impedance bandwidth with upper segment of lower permittivity. Quarter wave (λ/4) transformer is used to design corporate feed line with equally distributed power in each arm. With this setup a 10 dB return loss impedance bandwidth up to 19% (5 GHz-6.1 GHz) is achieved.Simulation of the four elements array antenna is performed using Computer Simulation Technology (CST 2010) and fabricated on Roger RO4003 substrate with εs= 3.38. A good agreement between simulation and measurements results is achieved.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121490899","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}

Therefore, to estimate the emissivity of the calibration source is a very important work. However, for a finite-size calibrator, the method capable of accurately calculating its emissivity has not been reported before our work. This paper presents our efforts in finding the accurate calculation methods of the emissivity for finite-size objects.

In the proposed method, resistances are loaded at the radiation terminal of tapered slot antenna where the loaded elements will slightly affect the main pulse and dramatically suppress the trailing pulse, and loaded elements joined by metal strips are directly connected to the radiation terminal, which will conduct most of the non-radiated energy into the loading tracks. Simulation results show that the loaded resistances can absorb currents which otherwise will be reflected at the radiation terminal to form trailing pulse, and connection of loading tracks in different radiators will improve reflection characteristics in lower frequency to enlarge the impedance bandwidth.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123349401","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 monopole strip serves as a feed for the monopole slot and also functions as an efficient radiator. The monopole slot generates a quarter-wavelength slot mode in the antenna's lower band, while the monopole strip contributes its quarter-wavelength mode in the antenna's upper band. By including a vertical strip which can be enclosed inside the handset casing or be a part of the bezel surrounding the periphery of the handset casing and connected to the bottom edge of the system ground plane, the impedance matching of the excited slot mode can be greatly improved. With a small board space of 9 × 40 mm2, the proposed antenna can cover penta-band WWAN operation.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122772287","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}
