Abstract

A single‐feed TM~21~‐mode circular patch antenna with circular polarization (CP) is proposed and investigated. The operating condition for CP in the antenna is theoretically determined and experimentally validated. An impedance bandwidth of 10% (SWR ≀ 2) and an axial ratio bandwidth of >2% (≀3 dB) have been obtained. The radiation patterns are stable over the operating band. Β© 2002 Wiley Periodicals, Inc.

The design of a single-feed, reduced-size circularly polarized circular microstrip antenna with four slits equally spaced and inset at the boundary of the circular patch is experimentally in¨estigated. Results show that by increasing the slits' lengths to be about 0.8 times the disk radius, the circ

## Abstract A novel design of a microstrip patch antenna with switchable branches is proposed to achieve circular polarization diversity. Two branches are incorporated into the patch and two switches are utilized to switch the branches on and off. By turning the switches on or off, this antenna can

## Abstract A single‐fed elliptic dielectric resonator antenna is designed for circular polarization. The feed is a coaxial probe chosen with the proper parameters to achieve wideband matching and good circular polarization properties. The analysis is performed numerically using WIPL‐D. The single‐
