Abstract
A repeater system is disclosed including a first planar antenna array comprising a first plurality of patch antennas, wherein the first plurality of patch antennas include a first pair of first patch antennas and a second pair of patch antennas, the first patch antennas in each pair disposed symmetrically about a perpendicular plane bisecting a distance between the patch antennas in each pair. Two microstrip antenna probes may be connected to respective ones of the first patch antennas in each pair. The two feed signals connected to the two probes may be phased shifted approximately 180 degrees out of phase with respect to each other. The repeater also includes a second planar antenna array comprising a second plurality of patch antennas and a housing connecting the first planar antenna array and the second planar antenna array. In some embodiments, each of the first planar antenna array and the second planar antenna array include some even number of E-shaped patch antennas.
