Meandered micro-strip patch antenna for UWB applications

Abstract

The project encompasses, design of rectangular micro-strip patch antenna for UWB frequency range. The designed antenna covers entire UWB specified by FCC i.e. 3.1-10.6 GHz. The antenna has been optimized for minimum possible dimensions i.e. a rectangular patch of 16 mm x 21 mm and ground plane of 35 mm x 30 mm fed with a micro-strip line of 13 mm x 3 mm covering the desired band. The chosen center frequency for design is 5.78 GHz basing on the geometric mean of FCC specified UWB. The concepts of bandwidth enhancement are reflected through physical application of some of the bandwidth enhancement techniques i.e. Meandering, Edge Truncation, and Ground Plane reduction. The parameters for which the design has been analyzed and optimized are Return loss, VSWR, Gain, Radiation pattern and Surface Current Density as per the international standards. Primarily Ansoft HFSS has been used as the designing tool for the antenna designing process. The optimized final design has been fabricated and tested at SMRIMMS. Results obtained thus conform to the simulated data thereby meeting international standards of an operating antenna device.
