Dual polarized Tightly Coupled Dipole Array (TCDA) for UHF to millimeter wave applications

We present a dual polarized Tightly Coupled Dipole Array (TCDA), representing the first practical realization of dual polarizations using a TCDA topology. This is accomplished through a dual-offset, split unit cell with minimized inter-feed coupling. The array achieves a minimum 6.1:1 bandwidth for VSWR<;2.25, 2.5, and 3.9 for 0°, 30°, and 60° scans, respectively. To our knowledge, this implies our design is simultaneously the widest band and widest scanning dual-polarized, conformal array in the literature.
