A Wideband Circularly Polarized Tightly Coupled Array [PDF]
IEEE Transactions on Antennas and Propagation, 2018 Tightly coupled arrays (TCA) have received considerable\ud interests recently. Although various TCAs have been reported, they are\ud limited to single or dual linear polarizations. Considering the importance of\ud circular polarization (CP) in various wireless systems, it is meaningful to\ud design a CP TCA with a simple configuration.
