ABSTRACT:
An antenna device includes an enclosure defining a receiving compartment and having a back forming a mounting seat for mounting to a fixture and an end forming a connector for connection with a coaxial cable. A reflection case, which is received in the enclosure, includes reflection plates set around the case and has a bottom stamped to form partially cut tabs that are bent upward by an angle of approximately 90 degrees. The diamond-shaped antenna is composed of two quadrilateral antenna boards received in the reflection case and fixed to the bent tabs and has a central portion to which a waveguide is coupled for connection with the connector of the enclosure through a coaxial cable. The enclosure is closed by a cover plate to protect the diamond-shaped antenna from direct exposure to severe weather.
