Design and Analysis of a Microstrip Patch Antenna for TV White Space Data Applications

The increasing number of smart and wireless devices demandsfor a more flexible allocation in the higher frequency spectrum. Dynamic spectrum access isone of the major candidates tosolve the problem of spectrum scarcity. TV white spaces(TVWS)provide a means to opportunistically use the underutilized TVfrequency bandsin consideration with the gradual switching of the traditional TV broadcast to digital broadcasting.With smart devices in mini, micro, or nano circuit packaging, one of themajor challenges is in thedesign of compact transceiver antennassuitable for mobiledevices that operates in the Ultra High Frequency (UHF)band.This paper provides a brief overview of TVWS and aproposedmicrostrip patch antenna design.Thegeometric measurements and the antenna parameters were designedand simulated in MATLAB. Results show a resonant performance at the 638 MHz operating frequency and a high front-to-back power ratio in the radiation pattern. The radiation characteristics are almost omni-directional in the azimuth while directional in the elevation plane. There is a minimal radiation at the back hence, for thin and slim devices, this will suit the desired application
