Title:

MESH REFLECTING MIRROR ANTENNA

Document Type and Number:

Japanese Patent JPH0486106

Kind Code:

A

Abstract:

PURPOSE: To make the weight of the reflecting mirror light by forming a wider mesh interval toward the circumferential part of the mesh reflecting mirror.

CONSTITUTION: A mesh interval S is formed narrow in the middle of a reflecting mirror 14 used at a high frequency band and the mesh interval S is formed wider at other part, i.e., the circumferential part of the reflecting mirror 14 on a same plane. In this case, the mesh interval S in the middle of the reflecting mirror 14 is set based on a high frequency band and the mesh interval S at the circumferential part is set based on a low frequency band. Then a radio wave at a high frequency band radiating from a primary radiator 12 radiates only to the middle part of the reflecting mirror 14 only, but a radio wave at a low frequency band radiates to the entire face of the reflecting mirror 14.
