Analytical expressions for the calculation of optimal operating frequency and the absolute moisture content derived from effective permittivity are presented. The influence of the order and the number of fractal curves used to the sensor characteristics are analyzed.

The proposed antenna is designed on a substrate RT/duroid 6006 with thickness of 1.27 mm and relative permittivity (εr) of 6.0 to operate in UWB band released by FCC in 2002 (i.e., 3.1–10.6 GHz). To reject the frequency band of 5.15–5.825 GHz, which is limited by IEEE 802.11a and HIPERLAN/2, an inverted-U-shaped strip is parasitically attached to the feed layer. The size of our proposed antenna is 45×50 mm2, which results in desirable radiation characteristics. Effects of varying the parameters of parasitic inverted-U strip on performance of proposed antenna have been studied. The antenna with optimal parameters obtained from parametric study is fabricated and measured. It is observed that the simulation and experimental results have good agreements with each other.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128484293","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 simulated results show that the antenna operates at (1.2GHz–2.9GHz) and (5.1GHz–6.1GHz) which includes the following applications: DCS(1.71–1.88GHz)/PCS(1.85–1.99GHz)/UMTS(1.92–2.17GHz) cellular bands, the 2.4/5.2/5.8GHz WLAN bands and finally the 2.5/5.5GHz WiMAX bands. The symmetrical geometric structure of the antenna provides omnidirectional radiation patterns.

Such three ports can be cascaded to form input and output manifolds for parallel or series connection of channel filters to form multiplexers. By incorporating switches into the filters it is possible to form switched multiplexers. The approach enables design of contiguous channels, thus avoiding the necessity of formation of even and odd numbered channels for preventing channel interactions in various switch combinations.

A previous design was introduced by Xiulong Bao & M. J. Ammann in 2008, it operates at 1.5 GHz and 2.6 GHz where the radiated fields are circularly polarized at these two bands. The proposed design in this paper is a modified version of the previously proposed one by adding a conductor rectangle at the end of the microstrip feed and etching three more slot arms in the ground. The modifications proposed in this paper enable the antenna to operate at three bands instead of two as in the previous design. This proposed antenna operates at the two bands of GPS systems (at 1.2 GHz and 1.575 GHz), and at the UMTS band (at 2.03 GHz). The radiation is circularly polarized at each band. For the first two bands the wave is RHCP while for the third band it is LHCP. A comprehensive numerical sensitivity analysis has been done to discuss the effects of various dimensional parameters and to optimize the performance of the designed antenna using an accurate simulation tool. The dielectric substrate used in the fabrication process is the FR4 material, of relative permittivity 4.4 and of thickness=1.5 mm. The fabricated antenna is measured in the microwave lab in the GUC. The simulated and measured results for the return loss show a good agreement.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116169069","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}

An effective relative permittivity greater than 13 can be reached for a 50-Ω characteristic impedance transmission line, leading to a slow-wave factor higher than 2. Additionally, low characteristic impedance transmission lines can be obtained without critical dimensions compared to classical coplanar waveguides.
