Abstract
A directional coupler for co-located antennas contemplates coupling a first transceiver to an antenna through a directional coupler. A second transceiver is also coupled to the antenna using the directional coupler. When the first transceiver is transmitting, the second transceiver may receive through the antenna without suffering interference from signals transmitted by the first transceiver. To facilitate signal handling, a tunable or variable load may also be coupled to the directional coupler.
Claims20
A device comprising:
- a first transceiver;
- a first directional coupler coupled to the first transceiver;
- a first antenna coupled to the first directional coupler;
- a second antenna;
- and
- a second transceiver coupled to the first directional coupler and the second antenna, the second transceiver comprising a control circuit, the control circuit configured to select between the second antenna and the first antenna, wherein when the first antenna is selected, no signal from the second antenna is used by the second transceiver.
