A Wideband Dual Linear/Circular Polarized 64-Element Phased Array Antenna for SATCOM Applications
Abstract
In this paper, a flat panel 8x8 phased array with a radio frequency integrated circuit (RFIC) based beamforming network (BFN), is proposed. The array works in dual linear in addition to dual circular polarizations over a bandwidth of 22-28 GHz, with a realized gain of 22-23 dBi/dBic in the broadside direction. The array achieves better than 3dB scan loss to ±50° and offers axial ratio (AR) below 3dB over the entire bandwidth within the proposed scan range. The array is comprised of innovatively engineered radiating elements, arranged distinctively in a 2x2 subarray level, thereby improving cross-polarized fields and axial ratio.
