DUAL ROLE ANTENNA ASSEMBLY

摘要

A dual role antenna assembly operable for use with GEO and LEO/MEO satellites has at least two curled inverted-F substantially omnidirectional antennas mounted on a ground plane. The antennas have asymmetrical gain patterns favoring certain sectors and are oriented such that the favored sectors of the different antenna face different directions. A controller selects the antenna for connection to an RF front-end in accordance with predetermined performance criteria.

1. A dual role antenna assembly operable for use with GEO and LEO/MEO satellites, comprising:
a ground plane; at least two curled inverted-F substantially omnidirectional antennas mounted on the ground plane, said antennas having asymmetrical gain patterns favoring certain sectors, and said antennas being oriented such that the favored sectors of the different antenna face different directions, and an RF beam selection switch for selectively connecting said antenna to an RF front-end; and a controller controlling said RF beam selection switch to in accordance with predetermined performance criteria.
