© 2016 IEEE. A millimeter-wave 16-element 44/60-GHz concurrent dual-band phased-Array front end capable of two-dimensional scanning with orthogonal polarizations for wireless communications and sensing has been investigated. Simulated results of the phased array front end show its concurrent performance at 44 and 60 GHz. In the receive (RX) mode, it has noise figure of 7.3/7.1 and 7.4/7.2 dB at the radiating elements and total array gain of 9.9/14.1 and 7.8/11.7 dB for the horizontal (H)/vertical (V) polarization at 44 and 60 GHz, respectively. In the Transmit (TX) mode at 44 and 60 GHz, it achieves a radiated power of 14.7 and 13.8 dBm at each antenna element and total gain of 21.4 and 10.4 dB for H-or V-polarization, respectively. The phased array also achieves ultra-high isolations of 75/73 dB and 120/118 dB at 44/60 GHz from TX to RX for H-and V-polarization, respectively.
