Abstract :
A 60GHz 4×4 circular polarized (CP) patch array antenna with a 90nm CMOS OOK modulator are integrated in low temperature co-fired ceramic (LTCC) substrate to form a SiP transmitter. The CP array shows a 3dB axial ratio (AR) bandwidth of over 8GHz. It has a 3dB beamwidth of 20° and a peak gain of 16.8dBi. Device modeling at 60GHz is done to accurately simulate the lumped components. The CMOS modulator includes a 60GHz oscillator and switchable amplifiers to provide the OOK modulation. The final fabricated 60GHz SiP transmitter prototype measures only 22×13×1.4mm3.
