摘要
PURPOSE: A plane patch antenna and a plane patch array antenna are provided to reduce a radar reflection area by absorbing an incident electromagnetic wave of a search frequency band of the radar. CONSTITUTION: A plane patch antenna comprises a cycle grating pattern layer(31), a metal patch(32) and a dielectric layer(33). The cycle grating pattern layer is formed on the electromagnetic wave incident surface or the center of the dielectric layer. The cycle grating pattern layer is designed to change the impedance of a plane patch antenna into the impedance of the free space. The cycle grating pattern layer is made of conductive polymer. The metal patch is formed on the electromagnetic wave incident surface of the dielectric layer to be connected to the feed part.
