PATCH ANTENNA OF SMALL AND LIGHTWEIGHT

摘要

PURPOSE: A small sized and light weight patch antenna is provided to manufacture a light weight antenna, which utilizes a low dielectric, by using a radiation patch which coats a conductive coating layer on a non-conductive material where a patterned groove is formed. CONSTITUTION: A predetermined dielectric substrate(10) is prepared. A radiation patch(20) is located in the upper part of the dielectric substrate. The radiation patch radiates an electromagnetic wave to the outside by receiving power from a feeder(40). An earth plate(30) grounds the radiation patch. A patterned groove(2) is formed in the lower part of the radiation patch.
