ABSTRACT:
A planar antenna in multilayered arrangement of a grounding conductor plate, a power supplying circuit plate and a radiating circuit plate being separated from one another. Radiating elements of the radiating circuit plate are a plurality of apertures electromagnetically coupled to power supply probes of the power supplying circuit plate. On the radiating circuit plate, a polarizer capable of converting linear polarized waves into circular polarized waves is provided, whereby the antenna is enabled to ensure a high efficiency and wide-band cross polarization characteristics.
