Hexagonal dielectric resonator antenna (HDRA) for multifrequency operation is proposed and investigated experimentally. The proposed antenna, excited by a single coaxial feed, resonates at four frequencies centered at 2.215, 2.784, 3.445, and 3.955 GHz with identical polarization. The return loss, VSWR, bandwidth, radiation patterns and half‐power beam width are measured and discussed. Multiple resonances with the same polarization and broad radiation patterns suggest the suitability of the antenna for multifrequency wireless applications. © 2006 Wiley Periodicals, Inc.
