Abstract
An aperture coupled microstrip patch antenna coupling circuit. Electromagnetic energy propagating along a stripline feedline is coupled through one of the ground plane surfaces through a tuned aperture to an adjacent microstrip feedline device, which may be a microstrip patch antenna. Undesirable propagation modes are suppressed by enclosing the aperture-coupled slot in a non-resonant cavity. Impedance matching is accomplished with an impedance matching section.
