The main focus of this work is the design of a Ka band circularly polarized planar array antenna. The design is based on slotted waveguide structures which offer an advantage of lower mechanical height that is well suited for nomadic terminals to communicate with satellites. Slotted waveguides also seem to exhibit relatively lower losses in the feeding network and their applications have been found in high power and planar array structures. The antenna is designed for the reception of satellite link (19.7-20.2 GHz).
