Design and Analysis of Dielectric Resonator Antennas For WLAN Applications

Sahoo , Chinmaya (2013) Design and Analysis of Dielectric Resonator Antennas For WLAN Applications. MTech thesis.



The increasing use of wireless mobile communication systems demand the antennas for different systems and standards with properties like reduced size, broadband, multi band operation, moderate gain etc. The planar and dielectric resonator antennas are the present day antenna designer’s choice. However, micro strip and Dielectric resonator antennas inherently have a narrow bandwidth. Since the Federal Communications Commission (FCC) first approved rules for the commercial use of ultra-wideband (UWB) in 2002, the experiments on ultra wide band (UWB) systems have been expanding rapidly. In this thesis, a low-cost compact microstrip line-fed antenna with parasitic patches resulting a Ultra-Wideband characteristics with a band dispensation is presented. The antenna was implemented on FR4 substrate with a thickness of 1.6mm & relative permittivity (µr) of 4.3 .It has a partial ground plane .The antennas is exited by microstrip line feed. The proposed antenna is a Rectangular shape , “T” shape,& “ð” shape made of Teflon of permittivity (µr) of 2.1& compare with “ð” shape made of Roger of permittivity (µr) of 10.2 .The proposed antenna is simulated with CST Studio 2011. The return loss results and radiation pattern plots of the antenna are included in this thesis.
