Differential RF front-end components provide greater immunity to ground noise and distortion by suppressing external interference. Recent advancements in differential RF front-end components offer high dynamic range, high input linearity, and low noise in the transceiver chain. However, differential phased arrays are not inherently ultra-wideband (UWB). To create a wideband differentially fed array, a novel approach is introduced by building on the well-established UWB Tightly Coupled Dipole Array (TCDA). This differential TCDA (D-TCDA) is proposed for S-Ku band (3-18 GHz) communications with emphasis on dual-linear polarization and wide-angle scanning. The array achieves 6:1 bandwidth for VSWR < 3 at broadside with scanning down to 45° from boresight in the E and H planes. It also exhibits very high polarization purity of 55 dB and port to port isolation exceeding 60 dB. Array simulations are verified with measured results of a similar 8×8 prototype.
