We have already proposed an accurate permittivity estimation method for a homogeneous dielectric object based on the geometrical optics (GO) approximation, where dielectric boundary points and their normal vectors are directly reproduced by the range point migration (RPM) method. In addition, the finite-difference time domain (FDTD) based waveform reconstruction method was incorporated to compensate for errors incurred by the GO approximation. This paper shows the experimental investigation of this method, where the new approach for suppressing the creeping wave along dielectric boundary is introduced. The results from real observation data validate its effectiveness, in terms of highly accurate permittivity estimation and buried object boundary reconstruction.","PeriodicalId":354277,"journal":{"name":"2014 International Symposium on Antennas and Propagation Conference Proceedings","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123130178","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 microstrip BPF is comprised of 2 pairs of 3 cascaded OSRR connected with microstrip lines. Here, the incorporation of square groundplane window underneath the OSRR is applied to improve the passband bandwidth response of proposed BPF. In the design process, some parametrical study is performed to optimize the BPF in achieving the optimum bandwidth response. The proposed microstrip BPF is then realized on a 0.8mm thick FR4 Epoxy dielectric substrate with the dimension of 35mm × 60mm. The measurement result shows that realized microstrip BPF has the bandwidth response of 1.12GHz ranges from 1.50GHz to 2.62GHz which is comparable with the design result.","PeriodicalId":354277,"journal":{"name":"2014 International Symposium on Antennas and Propagation Conference Proceedings","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116671595","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 proposed antenna is composed by a directed-fed monopole and two coupled strips.

The first wideband obtained cover GSM850 (824-894 MHz), GSM900 (880-960 MHz) and is produced by the directed-fed monopole. The second wideband goes from 1710 MHz to 2690 MHz, covering DCS (1710-1880 MHz), PCS (1850-1990 MHz), UMTS (1920-2170 MHz), LTE2300 (2300-2400 MHz) and LTE2500 (2500-2690 MHz), is caused by the introduction of the coupled-fed strips on the antenna.

The proposed loop antenna consists of an impedance transformer which is printed on a 1.0 mm FR4 substrate and the exterior metal ring of a mobile device. The loop antenna is fed from the end of the impedance transformer, and then was connected with the exterior metal ring to excite a half-wavelength loop resonant mode. Through the adjustment of the length and width of impedance transformer, the good impedance bandwidth was obtained. Due to its integrated structure with exterior metal ring and simple design concept, the proposed antenna is very suitable for the GSM900/1800 antenna application of a mobile device, especially in a mobile smart phone.

In the analysis of radio propagation characteristics, a λ/2 dipole antenna is assumed to be the wave source in many cases. However, it is necessary to analyze radio propagation characteristics considering the car body. The reason why is that the directivity of car antenna is changed due to the effect of car body. Additionally, the directivity of car antenna is also changed by the effect of antenna position on car body. In this paper, the effect of car antenna position on radio propagation characteristics at a blind intersection is investigated. Here, the hybrid method using both the FDTD and ray-tracing methods is used for the electromagnetic analysis.","PeriodicalId":354277,"journal":{"name":"2014 International Symposium on Antennas and Propagation Conference Proceedings","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125849219","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}
