This article presents two compact circularly polarized microstrip antennas with a very wide 3 dB axial ratio bandwidth and triple circularly polarized bands. A hexagonal stub (circular polarization element) along with tuning element in the ground plane is used for achieving wide 3 dB ARBW in antenna-1, while a novel approach of using a parasitic strip around the circular polarization element is used in antenna-2 for introducing band elimination notches in the circularly polarized band of antenna-1. The antenna-1 has a 210 dB impedance bandwidth of 12.34% (3.8-4.3 GHz), 84.02% (4.9-12 GHz), and 3 dB ARBW of 79.94% (4.9-10.9 GHz). The antenna-2 displays circularly polarized band elimination notch characteristics with 210 dB impedance bandwidth of 24
