In this paper, we present a novel dielectric EBG corner reflector antenna. The reflector is realized using dielectric rods arranged in a square lattice. The influence of reflector width, length and source distance from the corner apex is investigated using a simple two-dimensional antenna model; results are then used to design a threedimensional antenna. A prototype was build and tested, showing a good agreement between simulations and measurements results: 40% impedance bandwidth is achieved as well as stable radiation patterns with a maximum gain of 13.5 dBi and a front-to-back-ratio greater than 20 dB. © 2010 VSP.
