To achieve complete coverage with a minimum s-band antenna gain of -7 dBi, a straightforward configuration utilizing dual circularly polarized microstrip patch antennas was employed. The configuration involved the implementation of a wide bandwidth, dual circularly polarized truncated corner microstrip antenna, which was complemented by two parasitic patches. To enhance the cross polarization bandwidth, diagonally embedded holes
