The invention relates to the field of wireless communication systems operating in a duplex mode for data transmission and reception and in particular to the millimeter-wave communication apparatus with high data throughput. The communication apparatus comprises a dual-polarized antenna with a corresponding first and second ports, optimized for the signal transmission on the first polarization and the signal reception on the second polarization wherein the two polarizations are essentially orthogonal to each other; the first independent filter that is dedicated to pass the signal in the first frequency band and suppress the signals in all other bands and the second independent filter that is dedicated to pass the signal in the second frequency band and suppress the signals in all other bands wherein the two frequency bands are not overlapping; transmitter and receiver radio frequency units for processing of the received or transmitted signal correspondingly to or from the digital modem. The first independent filter is connected to the transmitter radio frequency unit and to the first port of the dual-polarized antenna and pass the transmitted signal from the radio frequency unit to the antenna. The second independent filter is connected to the receiver radio frequency unit and to the second port of the dual-polarized antenna and pass the received signal from the antenna to the radio frequency unit. The invention can be implemented in point-to-point radio relay communication systems to provide combined polarization-division and frequency-division duplexing of the transmission and reception with reduced insertion loss level and higher isolation level between the transmitter and receiver. Implementation of the invention allows to achieve the required isolation level between the transmitter and the receiver with the reduced insertion loss level.
