摘要：

In this letter, a circular polarized dielectric resonator antenna (DRA) using notched resonators excited through narrow slots is presented. To improve the gain, the slot positions were determined based on the characteristic of standing wave ratio over a short ended microstrip feeder. To enhance the bandwidth and circular polarization, three notched rectangular dielectric elements were rotated 45 degrees with respect to the sides of the exciting slots. The DRAs are modeled as a parallel RLC component, as that will be used to determine the dielectric resonator dimensions. Antenna characteristics of the array antenna including return loss, radiation patterns, and antenna gain are presented. The size of the whole antenna structure is 40 x 45 mm2 which gives its potential use in wireless communication systems. (C) 2012 Wiley Periodicals, Inc.
