Polarization Diversity Antenna for Receiving Traffic Information Contents in WiBro System
Abstract
Diversity antenna system against multi-fading environment is strongly required for WiBro service of vehicle. In general, high isolation performance between antennas leads to good diversity gain. In this paper, a polarization diversity antenna is presented, which has orthogonal polarizations and good isolation characteristic. In addition, by simulation and measurement, it is certified that HWLLA (Half Wave Length Loaded Antenna) improves polarization purity on common ground. In isolation between two antennas, HWLLA can provide better isolation over 12dB than conventional PIFA (Planar Inverted F Antenna).
