CIRCULAR POLARIZATION MICROSTRIP PATCH ANTENNA AND ARRAY ANTENNA USING THE SAME

摘要

PURPOSE: A circular polarization microstrip patch antenna is provided to increase a radiation efficiency and to reduce a fabrication cost by connecting the first patch and the second patch with a form layer interposed therebetween. CONSTITUTION: The first patch antenna layer includes a dielectric layer(120) and a ground conduction layer(110) and radiates an energy by exciting a current through a power feed part(130) which is connected with the first patch(140) placed on one side of the dielectric layer. Tee second patch antenna layer includes a dielectric film(160) and radiates an energy by exciting a current through the first patch which is connected with the second patch(170) placed on one side of the dielectric film. The first form layer(150) is disposed between the first and second patch antenna layers to isolate the first and second patch antenna layers. The second form layer(180) is disposed on one side of the second patch antenna layer to protect the second antenna layer.
