A circularly polarized microstrip patch antenna using circular parasite patches

A circularly polarized microstrip patch antenna with circular parasite patches with a simplified feed network is discussed in this paper. It can operate in the frequency which comes under x band that is from 8-12 GHZ. One of the most common types of antennas used in satellite communications is the microstrip patch antenna. It is comprised of a metallic “patch” on top of the dielectric substrate and the ground plane underneath the dielectric material. The axial ratio and other parameters are improved by using circular parasitic patches. The dimensions of the propounded antenna are 0.93λ0× 0.93λ0 × 0.017λ0 (whereλ0 is the space wavelength proportionate to the center frequency of 10.4 GHz).
