Abstract:
A circuit includes an antenna, and a pair of transceivers. A first transceiver in the pair is connected to the antenna via a first pair of feed-points, and is designed to transmit and receive signals in a first band of frequencies. A second transceiver in the pair is connected to the antenna via a second pair of feed-points, and is designed to transmit and receive signals in a second band of frequencies. The first band and the second band are non-overlapping frequency bands. The first pair of feed-points is located at a voltage null point of the antenna with respect to the second pair of feed-points. The second pair of feed-points is located at a voltage null point of the antenna with respect to the first pair of feed-points. The first transceiver and the second transceiver are, thus, enabled to simultaneously transmit and/or receive corresponding signals using the same antenna.
