ABSTRACT:
A radome includes a radome member formed of a dielectric to protect an antenna element from outside space and a structural member formed of metal for supporting the antenna element at the center thereof and to which the radome member is joined at the periphery of the antenna element to support the radome member. When the radome member is formed of dielectric and the structural member is formed of metal, the junction therebetween serves as a kind of antenna and the radiation characteristic of the ordinary antenna element is disturbed. To solve this problem, a portion of the radome member through which an electric wave is transmitted is formed of material through which an electromagnetic wave having a frequency identical with that of the electric wave is transmitted and a junction formed between the radome member and the structural member has a structure for absorbing the electric wave.
