1. In a wireless communication device, an antenna system comprising:
- two or more conductors combined to extend about a periphery of the wireless communication device, said two or more conductors comprising at least a first conductor and a second conductor;
at least a first coupling region, wherein the second conductor is spaced apart from and configured to overlap with the first conductor to form the first coupling region therebetween;
a first parasitic element disposed adjacent to the first and second conductors at the first coupling region, the first parasitic element being coupled to ground; and
an antenna feed coupled to the first conductor at a feed junction, the antenna feed being coupled to each of;
an active tunable component and a tuning loop;
wherein the active tunable component is adjustable to vary a frequency response of the antenna.

Abstract
The disclosure concerns a beam steering antenna system that can be integrated into a portion of a mobile device, such as a ring conductor that encompasses the device or traverses a portion of the periphery of the mobile device. The single port antenna is capable of generating multiple radiation modes which possess different radiation pattern characteristics. An offset parasitic is implemented to couple to the main radiating element and alter the current distribution to affect a change in radiation mode. The coupling typically occurs at a coupling region designed into the conductive ring used as the antenna in a wireless device.
