Antenna device with a controlled directional pattern and a planar directional antenna

Abstract

The invention relates to antenna systems used in local wireless communications networks. The antenna system includes planar directional antennas (), each of which is made as a dielectric plate (), with an active element () of the antenna () mounted on said plate. The surface of the plate () that faces the active element is metallized and serves as a reflector () of the antenna (). The plates () are interconnected along their edges in such a way as to form lateral facets of a hollow frame () of the device. The end face () is made as a dielectric plate () with the external surface metallized and can also contain an active element () of the antenna (). An antenna commutation switch () connected to a switch control unit () and to active elements () of the antennas () is mounted on the inner surface of the end face () of the frame (). Active element () is mounted on said plate by means of pins cut in the body of the active element () and bent during mounting. This invention permits to manufacture structurally simple and inexpensive antennas and antenna systems based on printed circuits and to exclude manual operations from the manufacturing and assembly of said antennas and antenna systems.
