Abstract
A repeater system is disclosed including a dual-fed donor patch antenna with a first microstrip antenna probe and a second microstrip antenna probe, phase shifting circuitry connected to the first microstrip antenna probe and the second microstrip antenna probe, wherein the phase shifting circuitry is 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. The repeater system also includes a coverage antenna (either a patch antenna or dipole antenna) and a housing connecting the dual-fed donor patch antenna and the coverage antenna. The housing is disposed to serve as a ground plane for the donor patch antenna and the coverage antenna.
