  • Multi-band antenna system
    Patent number: 7050018
    Abstract: A radio antenna having radiating conductors (28,30,32) which can be connected together by the action of antenna switch modules (20,22,24), whereby the electrical length of said antenna can be changed. Power and control signals to said antenna switch modules, are conducted from the antenna controller (18) through the feed line (14), and said radiating conductors. The radiating direction of said antenna can be changed by a directional switch module (74), which receives power and control signals through said feed line from a directional control circuit (29). Thus said antenna can be tuned for a plurality of frequency bands, and the radiating direction can be changed, by remote control.
