US 9,000,984 B2 · Multiple input, multiple output antenna for handheld communication devices

Abstract

An antenna assembly for a mobile wireless communication device has a support with a first surface and a second surface between which a third surface and a fourth surface extend. A conductive ground plane is formed on the second surface. An antenna includes an electrically conductive patch located on the first surface, and first and second electrically conductive legs and an electrically conductive stripe all abutting the patch. In one version the first and second legs and the strip are all on the third surface. In another version the first and second legs are on the third surface and the strip is on the fourth surface that is orthogonal to the third surface. A first signal port is adapted to apply a first signal to the first leg and a second signal port is adapted to apply a second signal to the third leg.

Dependent claims

An antenna assembly for a mobile wireless communication device comprising:

a support having a first surface and a second surface between which at least one side surface extends;
a conductive layer on the second surface;
and
a first antenna located on the support and comprising:
a first strip of electrically conductive material extending along an edge at which the side surface abuts the first surface, said first strip being of uniform width along said edge;
a second strip of electrically conductive material extending along the edge at which the side surface abuts the first surface and contiguous with the first strip and said second strip being of uniform width along said edge;
a first signal port connected at the first strip for applying a first signal to the first strip;
and
a second signal port connected at the second strip for applying a second signal to the second strip.
