MICROSTRIP ANTENNA WITH A CIRCULAR POLARIZATION FEATURE WHICH CAN BE USED IN BOTH A NEAR FIELD AND A FAR FIELD

摘要

PURPOSE: A micro strip antenna is provided to form a uniform vertical magnetic field in a near field while satisfying a circular polarization feature.;CONSTITUTION: A first dielectric substrate(120) is placed on a ground surface(100). A triangle patch main body(130) is printed on the bottom of the first dielectric substrate by strip lines. An electricity supply unit(140) is formed on one edge of the triangle patch main body. The electricity supply unit is connected to a coaxial cable connecting unit through an electricity supply line. A second dielectric substrate(150) is placed on the first dielectric substrate.;COPYRIGHT KIPO 2011
