Abstract :
A polarization diversity bi-directional antenna is proposed to be used as the cell station antenna in the expressway environment. The gain patterns are simulated by wire-grid modeling. The experimental radiation pattern and SWR agree reasonably with the simulated results which validates the accuracy of the wire-grid modeling. The bi-directional pattern and good diversity performance of this proposed antenna ensure that this antenna is a promising candidate for the cell station antennas in the expressway environment.
