Abstract :
Slot antennas fed by a circular waveguide or a cylindrical cavity have been developed. The slot antennas can be rectangular slots or cross slots. Radiation patterns have been measured for both slot configurations. The use of circular waveguides has many advantages, such as a symmetrical feeding arrangement and the realization of cross polarization feeding.<>
