Abstract :
A 60 GHz integrated four-element planar antenna array is developed. Each antenna is integrated with a sub-harmonic I/Q mixer based on APDPs for the convenience of high-speed signal processing such as adaptive beamforming. An average conversion loss of four channels of less than 10.6 dB is achieved. Amplitude imbalance and phase deviation between I and Q outputs of each channel are less than 2.5 dB and 7/spl deg/, respectively. The array is used to construct a digital beamforming system along with an IF circuit block and DSP modules. Beam scanning results are successfully demonstrated.
