LINEAR POLARIZATION ANTENNA WITH IMPROVED CIRCULAR POLARIZATION RECEPTION CHARACTERISTIC

摘要

PURPOSE: A linear polarization antenna with improved circular polarization reception characteristic is provided to implement improved circular polarization sensitive without changing the design of the antenna by improving a ground structure. CONSTITUTION: A linear polarization antenna(1) is comprised of a ground plane(10), a conductor(20), and a feeding unit(30). The ground plane is comprised of a finite plane conductor. A circuit transmission line is formed on the ground plane. A current supplied to a conductor is circulated around the conductor and is transmitted to the ground plane through the circuit transmission line. The conductor and the feeding line are formed at the center in upper part of the ground plane.
