Abstract :
A wideband low-profile, circular-polarized CNBLCP) phased array radiator has been developed for broadband phased array applications. The radiator is capable of providing common-phase-center circular- or dual-linear polarization, and wide scan volume over an octave bandwidth. These are all desirable features in today´s phased array antennas for multifunction radar and satcom applications. The design of a new WBLCP element is presented along with its predicted frequency and scan performance. These calculated results have been validated using waveguide simulator measurements. A comparison of the predicted and measured results is also presented.
