ABSTRACT:
A planar antenna for linearly polarized waves includes a grounding conductor plate, a power supply circuit plate having a pattern of power supplying circuit of 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 arranging the power supplying terminals of the power supplying circuit pattern as well as the apertures in the radiation plate so that the respective power supply terminals terminate to be within a contour of the apertures, in a top plan view, whereby the planar antenna makes it possible to receive at a high gain the linearly polarized waves over a wide band.
