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 20º and a peak gain of 16.8dBi. Device modeling at 60GHz is done to accurately simulate the lumped components. The CMOS modulator...
A 60 GHz 4 × 4 circular polarized (CP) patch array antenna with a 90 nm CMOS OOK modulator are designed and integrated in low temperature cofired ceramic (LTCC) substrate to form a SiP-based transmitter. By applying a stripline sequential rotation feeding scheme, the CP array exhibits a wide impedance bandwidth (VSWR<;2) and 3 dB axial ratio (AR) bandwidth, both over 8 GHz. It has a beam-shaped...
A 60-GHz wideband circular polarized (CP) patch array of 4??4 elements is designed and fabricated in low temperature cofired ceramic (LTCC) technology. By applying a strip line sequential rotation feeding scheme this array exhibits wide impedance bandwidth (VSWR<2) and 3-dB axial ratio (AR) bandwidth, both over 8 GHz. In addition, it exhibits a peak gain of 16.8 dBi and a beam-shaped pattern with...
