Abstract

In this paper, a miniaturized circularly polarized patch antenna with a stacked configuration for gain enhancement is presented. This patch antenna consists of a circular sector element with square notches. Normal circular sector patch antenna generates two different resonant modes. Theoretically, one mode induces a polarization that is perpendicular to the polarization of the second mode. In this study, these two modes are controlled by varying the size of the square notches allowing the generation of a CP. This time, the basic design and performances of such a circular sector patch antenna are numerically and experimentally discussed. It should be noted that the size of the proposed antenna is half the one of usual corner-truncated square patch antennas
