Abstract
Design of a Ka-band low loss circularly polarized omni-directional slot array antenna is presented. The slot array is conformal on a circular waveguide and the slots are radiating into a parallel plate region for circular polarization. Elevation beam is directed to +10 degrees for the required elevation coverage of -10°/+30°. Simulation results show that the return loss is better than 20 dB in 1% bandwidth. Gain of the antenna greater than 1 dBi and the axial ratio better than 4.2 dB in the full sector of coverage.
