The antenna is a V-shaped monopole fed by a microstrip line. The V-shaped design is modified from a reference antenna which contains a vertical and a horizontal arm fed by a microstrip line. By tuning the angle between the two arms, a critical angle yielding a broadband circularly polarized wave can be found. To improve the overlapped return-loss and axial-ratio bandwidth, a slit is cut on the ground plane. It is measured that the return-loss bandwidth is 23% and the axial-ratio bandwidth is 30%.
