ABSTRACT:
A surface wave microwave antenna is presented in which transmission or reception of microwave energy is effected by discontinuities in a dielectric body positioned between a central feeder element and a ground plane. When used as a transmitter, the central disc propagates surface waves in the dielectric body in expanding circles; and the discontinuities in the dielectric body act as radiating or scattering sites to couple the waves to free space. When used as a receiver, the reverse will occur.
