Enhancing mm-Wave Beam-Steering with Super Wideband Phased Array for Body Area Network

In order to meet the demands of 5G NR/FR-2 wireless networks frequency bands, it is crucial to develop super wideband (SWB) phased array antennas with wide-scan and advanced beam steering capabilities for high speed data transmissions. This research focuses on a new beam-steerable phased array architecture that offers a broad bandwidth for 5G Body Area Networks and wireless IoT devices. The proposed phased array design consists of eight radiators arranged in an 8×1 linear shape, each equipped with separate small strip-line feedings. The proposed antenna array, composed on a substrate of Rogers RT6002, measures 64 mm by 9.51 mm by 1.52 mm in physical dimensions. This design offers a straightforward design approach, low complexity profile, wide impedance bandwidth, and stable characteristics, with a simulated operational frequency span from 21GHz - 50 GHz and a super bandwidth of 29GHz with a -10 dB threshold.
