Patent ID: 8626057

Claim:
A repeater system comprising: a first planar antenna array comprising a plurality of first patch antennas, wherein the plurality of first patch antennas comprises a first pair of the first patch antennas and a second pair of the first patch antennas, wherein the first patch antennas in each pair of first patch antennas are disposed symmetrically about a perpendicular plane bisecting a distance between the first patch antennas in each pair of first patch antennas; a first microstrip antenna probe and a second microstrip antenna probe connected to respective ones of the first pair of first patch antennas; first phase shifting circuitry connected to the first microstrip antenna probe and the second microstrip antenna probe, the first phase shifting circuitry configured to: receive an input signal, supply a first signal to the first microstrip antenna probe, and supply a second signal to the second microstrip antenna probe using the input signal such that the first signal and the second signal are approximately 180 degrees out of phase with respect to each other; a second planar antenna array comprising a plurality of second patch antennas; and a housing connecting the first planar antenna array and the second planar antenna array.
