Abstract: Systems and methods which utilize a current null cut reflector dipole antenna configuration are shown. According to embodiments, a plurality of current null points are identified with respect to an antenna element reflector configuration whereby a reflector is provided which terminates at the identified current null points. Accordingly, a noncontiguous reflector is provided in current null cut reflector dipole antenna elements. The discontinuity in the noncontiguous reflector is utilized for disposing signal feed paths providing a feed network to the dipole antenna element of the current null cut reflector dipole antenna. Accordingly, current null cut reflector dipole antennas of embodiments may be provided in configurations which are relatively simple and inexpensive to manufacture, such as two-sided printed circuit board configurations.
