Wideband dual polarized antenna array system
Abstract:
A wideband dual polarized antenna array system, with minimal number of RF ports that enables wideband array frequency ratios of 25:1 to 120:1. Reduced grating lobe performance is enabled by employing antennas-within-antennas. Orientation and spacing of antennas in novel methodologies further reduces sidelobes and grating lobes. Finally, this technology reduces the number of RF ports, compared to Tightly Coupled Dipole Antenna (TCDA) arrays by 10× to 25× times.
