Abstract

The concept of a dual‐band dual‐circularly‐polarized antenna for GPS (Global Positioning System, 1575 MHz) and DAB (Digital Audio Broadcasting, 1452–1492 MHz) system is proposed. The generation of circular polarizations and reduction of an overall antenna‐element dimension are achieved by placing a partially filled high‐permittivity dielectric bar under the radiating edges of the patch. A patch‐antenna element based on the proposed method and a conventional antenna element with an air layer filling the whole volume under the patch are compared, and antenna‐dimension reduction of more than 30% is achieved using the proposed method. Finally, a sector‐type antenna is designed by employing the space‐diversity technique with the proposed antenna elements. © 2005 Wiley Periodicals, Inc.

## Abstract We designed and implemented a dual‐band square patch antenna with circular polarization for the reception of GPS and DMB. Resonant elements of 1.5‐ and 2.6‐GHz bands are entire square patch and inner square patch divided by slots, respectively. And impedance bandwidths (VSWR ≤ 2) are 61

## Abstract A spiral antenna with a helix loaded is investigated in this paper. Through combining the spiral with a helix together, circular polarization can be achieved in dual bands. Since the helix is loaded in the lower part of the spiral, this technique doesn't increase the antenna's volume bu
