Abstract :
A novel type of monopulse circular polarization radial waveguide slot array antenna (RWSA) at W wave band with good stability, small volume and low manufacturing difficulty is designed in this paper. The antenna consists of radial waveguide slot array planar antenna, rectangular-to-radial waveguide transformer and planar sum-difference network. The properties of the antenna are realized by using genetic algorithm and available electromagnetic simulation software HFSS.
