Paper Abstract

A circularly polarized waveguide antenna using a simple feed structure is proposed and investigated. The feed probe forms L character put on a sidewall of the waveguide so that circular polarization can be generated by the traveling wave on the L-probe. This paper describes the proposed scheme and the experimental CP characteristics of waveguide antenna. Finally, simulated results by finite-difference time-domain (FDTD) method are presented.
