1. A user device comprising:
a single radio frequency (RF) input; and a grounded patch antenna configured to operate as a dual-band antenna radiator, wherein the grounded patch antenna is formed of a metal member of the user device, wherein the metal member is three-dimensional comprising a first surface in a first plane, a second surface in a second plane and a third surface in a third plane, and wherein the grounded patch antenna comprises:
a coupled feed coupled to the single RF input at the first surface, wherein the first surface has a triangular shape, wherein the coupled feed is disposed at an edge of a hypotenuse of the triangular shape, wherein the first surface of the grounded patch antenna is disposed in the first plane parallel to a ground plane, and wherein the second surface extends from the first plane to the ground plane in the second plane perpendicular to the first plane and the third surface extends from the first plane to the ground plane in the third plane perpendicular to the first plane;a first slot radiator formed in the second surface of the metal member, wherein the second surface is a rectangular shape, wherein the first slot radiator is formed as a first slot opening in the second surface, the first slot opening not extending an entire length of the second surface; anda second slot radiator formed in the third surface of the metal member, wherein the third surface is a rectangular shape, wherein the second slot radiator is formed as a second slot opening in the third surface, the second slot opening not extending an entire length of the third surface. |
