ABSTRACT:
An antenna coupling assembly (100) includes an stub section (107) for coupling radio frequency (RF) energy from an RF source to a radio antenna. An antenna coupler ground (113) is positioned adjacent to the stub section (107) and is electrically connected to the ground of the RF source (101). In accordance with the invention, a ground extension section (115,115',115") is attached to the antenna coupler ground (113) for electrically extending the physical length of the antenna coupler ground to enhance efficiency and overall performance of the antenna coupler.
