due to the frequency dependence of phasing mechanisms applied in planar printed reflectors , when using planar printed reflector antennas beam squint occurs as the frequency is scanned within the operating band . in order to reduce or eliminate beam squint , an incident signal incident upon a reflector is altered in such a way that the outgoing signal retains a same direction . in an embodiment , this is achieved by providing feed elements in different locations , each feed element for feeding a signal of a different frequency . in another embodiment , two reflector arrays are used wherein beam squint caused by the first reflector array is compensated for by the second reflector array .
