ANTENNA INCLUDING A RADIATOR WITHOUT PLATING

摘要

PURPOSE: An antenna including a radiator without planting is provided to implement a beam pointing error, a beam tracking error and the isolation between polarized waves within an allowable range by arranging choke members between radiators. CONSTITUTION: A reflector(200) is connected to an external conductor(244) of a power cable(240). A first radiator(202) includes a radiation member(210,212), a feeding unit(214), a balun(balanced-to-unbalanced transformer)(216) and a first feed line(218). The first feed line is arranged in a first space of the feeding unit and a second space of the balun. A second radiator(204) includes a radiation member(230,232), a feeding unit(234), a balun(236) and a second feed line(238). The first radiator and the second radiator are arranged on a same insulating unit(206).
