Abstract :
This paper briefly presents a new approach to understanding arbitrarily-shaped microstrip antennas as supergain arrays of the main antenna and its images. Experimental validation is presented on several multi-layer antennas that have non-conventional shapes, such as diamonds and stars. In particular, we present the design and frequency scaling of a dual-polarized two-layer star antenna for use in polarization-diversity wireless links, in which the different shape of the patch allowed us to obtain better polarization properties than with a standard square design. Measured simulation and experimental results at 1.7GHz and a scaled version at 10GHz are shown.
