Original Abstract Submitted

a communications system may include a first electronic device and a second electronic device that communicate over a high speed short range wireless communications link. to support the link, each device includes one or more antennas that concurrently transmit(s) and receive(s) radio-frequency signals at the same frequency under an in-band full duplex (ibfd) scheme. one device may include a housing wall and a waveguide. the waveguide has an elongated portion facing the antenna(s) and a horn extending from the elongated portion. the waveguide may convey the radio-frequency signals between the antenna(s) and the other device through the wall. the waveguide may serve to mitigate signal leakage from a transmit port onto a receive port of the device while conveying wireless data over the high speed short range wireless communications link. in addition, the waveguide allows flexibility in configuring the antennas and enhances system robustness with larger alignment tolerances.
