Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The antenna module may comprise: a communication circuit; an antenna unit comprising a plurality of first antenna elements forming a sub-array; a feeding network unit that is disposed below the antenna unit, and is configured to provide at least one first transmission line that is branched to the positions of the plurality of first antenna elements so that the plurality of first antenna elements form the same phase; a mounting unit that is disposed below the feeding network unit, and comprises a plurality of vias such that transmit and/or receive power of the communication circuit is provided to the antenna unit; and a routing unit that is disposed between the feeding network unit and the communication circuit, and is configured to provide at least one second transmission line that extends from a position corresponding to an output end of the communication circuit to a position corresponding to an input end of the feeding network unit in at least one layer.

Abstract: An In-phase/Quadrature phase (I/Q) mismatch compensation method of a transceiver is provided. The method includes establishing a first loopback path between a transmitter and a receiver, transmitting a training sequence from the transmitter to the receiver through the established first loopback path, acquiring, at the receiver, a first correlation result value by correlating the training sequence received through the established first loopback path, establishing a second loopback path between the transmitter and the receiver, transmitting the training sequence from the transmitter to the receiver through the established second loopback path, acquiring, at the receiver, a second correlation result value by correlating the training sequence received through the second loopback path, and estimating I/Q mismatch values of the transmitter and the receiver using the first and second correlation result values.
