Abstract
An antenna system includes a ground plane, a microstrip-line coupler, a metal cover, and a main antenna. The microstrip-line coupler has a first input port, a second input port, a first output port, and a second output port. The metal cover is disposed above the microstrip-line coupler and coupled to the ground plane. The main antenna is coupled to the first output port and the second output port of the microstrip-line coupler. The metal cover is configured to reduce the interference from the microstrip-line coupler and to enhance the gain of the main antenna.
