ABSTRACT:
A mutual coupling neutralizer for neutralizing adverse mutual coupling between a pair of patch antennas for mobile communication system. The coupling neutralizer includes a first and second capacitor each having a first end and a second end, where the first ends are coupled to a respective patch antenna. The neutralizer further includes a high impedance transmission line connected to the second ends of the capacitors. The transmission line and capacitors are sized and configured to neutralize adverse mutual coupling between the pair of patch antennas over a predetermined frequency band. The neutralization of mutual coupling is achieved by extracting a signal present at one patch antenna and injecting the signal at the other patch antenna at a substantially equal amplitude and opposite in phase.
