Abstract : The use of dielectric filling in waveguide slot antennas is practiced mainly because of size and weight reduction. The equivalent circuits of a single radiating slot are discussed, and their lumped circuit elements determined. It is found that the behavior of a slot is retained while only the resonant length is shifted through dielectric loading. A new-method of achieving electronic scan of these antennas by continuous loading of a ferrite slab in the guide is discussed. Data are compiled on the propagation constants and losses of a uniform dielectric loaded waveguide over a wide range of operating conditions.
