Abstract (en)

Provided is a circularly polarized patch antenna using a metal patch and a transmitting/receiving array antenna. The antenna can induce impedance matching and improve axial ratio by using a simple metal radiating patch and a reflection plate and improving the electromagnetic connection characteristics between the reflection plate and the radiating patch. It has a simple structure and it can be produced at a low cost. The circularly polarized patch antenna includes: a radiating unit which is positioned in the upper part of the antenna and has a metal patch for transmitting/receiving circularly polarized signals; a reflecting unit which is positioned in the lower part of the radiating unit with an air layer of a predetermined space from the radiating unit and eliminates rear radiation of the radiating unit; and a power feeding unit for supplying power to the radiating unit.
