Abstract
A wireless device for full duplex radios (FDR) is provided. The wireless device includes an FDR transceiver and an antenna module. The antenna module has a plurality of antennas. Specific distances are designed among the antennas so as to cancel the self-interference to the received signal of the FDR transceiver from the transmitted signal of the FDR transceiver.
Claims22
A wireless device, comprising:
- a full duplex radios (FDR) transceiver, comprising a first transmit feeding point and a first receive feeding point, and being configured to transmit a first transmitted signal from the first transmit feeding point and receive a first received signal from the first receive feeding point;
- an antenna module, comprising:
- a first inverter;
- a first antenna coupled to the first transmit feeding point via the first inverter;
- a second antenna coupled to the first transmit feeding point;
- and
- a third antenna coupled to the first receive feeding point;
- wherein the first antenna and the third antenna have a distance d1,3 therebetween, the second antenna and the third antenna have a distance d2,3 therebetween, and a distance difference between d1,3 and d2,3 is substantially 0.
