A planar dual-polarized ultra-wideband millimeter-wave array antenna
Paper in proceedings, 2018

We present a dual-polarized ultra-wideband element in an infinite large array condition for planar phased array antennas in mm-wave applications. The array antenna consists of tightly-coupled bowties in a dual-offset configuration. In order to simplify the manufacturing process and eliminate the scalability limitation, a new feeding network is employed. The feeding is inspired by magneto-electric dipoles (MEDs) and planar ultra-wideband array antennas (PUMAs). Hence, the feeding is integrated with the horizontally oriented radiating bowties and removes the need for the external baluns. The simulated antenna shows relative bandwidths of 2.3 : 1 and 3 : 1 at VSWR<3, for maximum scanning angles of 60° and 45°, respectively, at both E- and H-planes.
