First Claim
1. An antenna assembly for a wireless communication device comprising:
- a printed circuit board having a dielectric substrate and a ground plane;
a first radiating element disposed on the printed circuit board;
a first port coupled to the first radiating element for applying a first signal that excites the first radiating element;
a second radiating element disposed on the printed circuit board and spaced apart from the first radiating element;
a second port coupled to the second radiating element for applying a second signal that excites the second radiating element;
a first meandering slot interposed on the ground plane between the first radiating element and the second radiating element; and
a third port coupled to the first meandering slot for applying a third signal that excites the first meandering slot to operate as a third radiating element.

Abstract
A multiple input-multiple output antenna assembly with high isolation between the antennas is disclosed. The antenna assembly includes a substrate with a ground layer at its surface. Two antennas are disposed opposing each other on the substrate. A meandering slot is interposed between the first and second antennas on the ground plane. A first signal port is provided for applying a first signal to excite the first antenna and a second signal port is provided for applying a second signal to excite the second antenna. The meandering slot provides isolation that inhibits electromagnetic propagation between the first and second antennas. A third signal port is provided for applying a third signal to excite the meandering slot to act as another antenna for multiple input, multiple output operation.
