Studies of Planar Antennas with Different Radiator Shapes for Ultra-wideband Body-centric Wireless Communications
This paper studies the performances of planar UWB monopole antennas using a radiator of different shapes including triangle,rectangle,square,annual ring,circle,vertical ellipse,ellipse,pentagon and hexagon for body-centric wireless communications.The planar antennas consist of a radiator and a microstrip-feed line on one side of the substrate and a ground plane on the other side.Results of simulation studies show that the antenna using an elliptical radiator appears to have a better overall performance in terms of bandwidth,gain,efficiency and radiation pattern,among the antennas studied.The antenna achieves a wide impedance bandwidth of 3.1-12 GHz,an average peak gain of nearly 3.5 dBi and good radiation patterns,making it a good candidate for UWB body-centric wireless communications.
