Abstract

The design of circularly polarized (CP) microstrip antenna with harmonics suppression is first proposed. The tapered defected ground structure (TDGS) has been utilized to obtain bandstop characteristics. The measured return losses at the second and third harmonic frequencies are βˆ’1.2 and βˆ’2.7 dB, respectively. The measured CP axial ratio is 0.8 in the broadside direction at 5.53 GHz. The details of the simulated and experimental results for the proposed design are presented and discussed. Β© 2007 Wiley Periodicals, Inc.

A new design for achie¨ing compact broadband circular ( ) polarization CP radiation of a square microstrip antenna is presented. The compactness of the microstrip antenna is easily obtained by inserting four slits of equal lengths at the patch edges, and broadband CP radiation is achie¨ed simply by
