Abstract

The design of a circular slot antenna for obtaining broadband circularly polarized (CP) radiation using a coplanar waveguide (CPW) feed is presented. The operation of the proposed antenna is achieved by protruding metallic mono‐strip from the circular ground plane towards the slot center at Ο• = 0Β° and feeding antenna using a 50‐Ω CPW with a protruded single strip at Ο• = 270Β°. In this design, the impedance bandwidth and 3 dB axial‐ratio bandwidth can reach as large as 50 and 36%, respectively. The peak of antenna gain is about 3.9 dBi, with gain variations <1 dBi for the frequencies within CP bandwidth. Β© 2007 Wiley Periodicals, Inc.
