Abstract
We present a 24–30-GHz 256-element dual-
polarization transceiver (TRX) phased array based on a
16-element beamformer integrated circuit (BF-IC), 2-element
frequency conversion integrated circuit (FC-IC), liquid crystal
polymer (LCP)-based combiners and filters, and a tileable
package with 64 embedded dual-polarized (dual-pol) antennas.
The phased array presented in this work overcomes three key
challenges in current 5G millimeter-wave (mmWave) antenna
arrays: 1) it supports a dramatic increase i
