摘要：
In this paper, design of compact broadband asymmetric slit Circularly Polarized (CP) Microstrip Patch Antenna (MPA) is presented for GPS and GLONASS application. Four asymmetric slits embedded sequentially in square patch, excites two orthogonal modes for CP radiation. Cross slot etched at the center of the patch to miniature the antenna. Four corners of radiating element truncated equally for further enhancing the Axial Ratio (AR) bandwidth. The realized antenna shows CP bandwidth of 45MHz (1.57 to 1.615 GHz) and gain of greater than 6.0 dBiC. The proposed antenna size is 0.307 lambda o X 0.307 lambda o X 0.008 lambda o.
