A novel technique for beam squint cancellation in planar reflectors

Due to the frequency dependence of phasing mechanisms applied in planar printed reflectors, such antennas are prone to beam squint as the frequency is scanned within the operating band. A novel technique is introduced in this paper to cancel the beam squint due to frequency sweep. Another reflector is used to cancel the beam squint within the operating band. The results are compared with the beam squint of a conventional planar reflector in order to demonstrate the effectiveness of the suggested technique.
