ABSTRACT:
A single dielectric substrate having formed thereon a plurality of planar antenna elements, and a ferrite substrate provided with a circulator are joined together to form a planar antenna module of an integral construction. The planar antenna elements are each composed of a patch formed by a thick or a thin film deposition technique. In one preferred form of joining, the dielectric substrate and the ferrite substrate are joined together at one side. In another preferred form of the joining, the ferrite substrate is fitted or assembled in an opening or window formed in the dielectric substrate.
