Abstract :
A novel circularly polarized microstrip helical antenna with broad impedance bandwidth and 3 dB axial ratio bandwidth is proposed based on traditional helical antenna. The helix is realized by connecting stacked multilayer microstrip circular arcs with vertical via holes. Details of the antenna analysis and design are described. Simulation results show that good radiation performance can be achieved.
