GPS/GLONASS RECEIVING PATCH ANTENNA CAPABLE OF EASILY HANDLING WITH THE CHANGE OF GROUND CONDITIONS AND AN ASSEMBLY THEREOF

摘要

PURPOSE: A GPS/GLONASS patch antenna and an assembly thereof are provided to flexibly control a resonant frequency and impedance according to the change of ground conditions and to solve the unbalance problem between power feeds according to a asymmetry station.;CONSTITUTION: An antenna mounting unit(60) is formed a shape in which a curved surface is extended in order to be installed a vehicle having a curved surface and comprises a front surface side mounting unit in order to be installed an antenna. A first radiation patch comprises a patch antenna installed on the front surface side mounting unit and is formed into flat type for acting in a first band. A second radiation patch is laminated in the lower part of the first radiation patch and is formed into flat type for acting in a second band. A first power feed pin(31) is arranged from the center of the first radiation patch to the side of the first radiation patch at the regular intervals. A second power feed(32) pin is arranged in order to accomplish constant angle about 1 power feed pin based on center.;COPYRIGHT KIPO 2011
