ABSTRACT:
A planar antenna includes a grounding conductor plate, a power supply plate having a pattern of power supplying conductor strips each including power supply terminals, and a radiation plate having apertures forming radiation elements, the respective plates being arranged sequentially with an insulating layer interposed between adjacent ones of the plates to separate them to be independent of one another through a predetermined interval, while coupling electromagnetically the respective power supplying terminals of the power supplying conductor pattern on the power supply plate to the radiation elements provided as the apertures in the radiation plate. With this simplified arrangement, the planar antenna makes it possible to receive at a high gain circularly polarized waves over a wide range.
