Patent ID: 7949310

Claim:
A radio transceiver module, comprising: a wave guide operably disposed within a dielectric substrate to conduct very high radio frequency (RF) electromagnetic signals; a first substrate transmitter communicatively coupled to a first substrate antenna which is coupled to the wave guide; second and third substrate transceivers communicatively coupled, respectively, to second and third substrate antennas which are disposed in the wave guide at different distances from the first substrate antenna, wherein the second and third substrate antennas are operably disposed to transmit and receive radio frequency communication signals, respectively, through the wave guide with the first substrate antenna; and a micro-strip filter having a plurality of selectable tap points, the micro-strip filter being electrically disposed to conduct a signal between the first substrate transmitter and the first substrate antenna by way of the plurality of selectable tap points, wherein each selectable tap point provides a corresponding filter response characterized by a resonant frequency for transmission through the wave guide, in which selection of a first tap point selects a first filter response to communicate between the first substrate antenna and the second substrate antenna and selection of a second tap point selects a second filter response to communicate between the first substrate antenna and the third substrate antenna.
