An Innovative 3D Metal Printed Dual Linear Polarized Dual Beam Tx/Rx Phased Array Heat Sink Antenna with Silicon RFIC Beamformers

A 4x2 dual beam, wideband, dual linear polarized phased array antenna, consisting of innovatively shaped all metallic radiators with an overall cross-section of λ/2 × λ/2 and height nearly equal to λ/2 corresponding to the center frequency (9.50 GHz), working also as heat sink is presented for X-band (8.5-11.5 GHz) applications. The peak broadside gain is varying between 14–11 dBi over the bandwidth. Peak gain varies from 12.8-12.5 dBi at 9.50 GHz as beam scans till ±45° in φ=00plane and ±30° in φ=90° plane. The 4x2 antenna aperture is 3D metal printed, and the beamforming network, comprised of Anokiwave RFICs, is integrated with the antenna aperture. The temperature reduction of 60°C is obtained using this heat sink antenna structure, which is validated with an infrared (IR) camera. The Anokiwave RFIC (AWS-0101) used here has the capability to excite both polarizations simultaneously, thereby is creating dual beam in two different directions simultaneously in receive mode.
