A Circularly Polarized Aperture Stacked Patch Microstrip Antenna for L Band

Progress In Electromagnetics Research C, Vol. 20, 95-109, 2011
Abstract
The design and manufacture of a circular polarized aperture stacked patch circular microstrip patch antenna (CPASPA) at L-band is presented. The Wilkinson power divider is used to excite the stacked circular patches by two orthogonal $H$-shape slots, which can improve the operation bandwidth and circularly polarized performance. The design is optimized by a series of parametric study of the input impedance for the antenna. The measurements show that the CPASPA has a 3-dB axial ratio (AR) bandwidth of 55.0% and a 10-dB return loss (RL) bandwidth of 47.0%. The measured gain is more than 0 dBic over the bandwidth of 42.5%, in which the maximum is 9.4 dBic. The measurements agree very well with the simulation results.
