This paper presents a dual-polarization antenna with high spectral efficiency for transmission application distance at 60 GHz. The dual-polarization antenna is integrated with the receivers through flip chip on the LTCC substrate at 60 GHz. The receiver front-end composes of a low noise amplifier and demodulator fabricated in 65-nm CMOS process. The conversion gain is higher than 14 dB and the noise figure is lower than 6 dB from 57 to 66 GHz. The total data rate of the proposed system's spectral efficiency is up to 12 bit/s/Hz for wireless measurement and the EVM is below 5.5 %.
