Antenna system coupled to an external device
First Claim
1. An antenna system, comprising:
- a wireless communication device including a housing portion, the housing portion enclosing electronic components of the wireless communication device;
a first antenna radiating structure disposed within the housing of the wireless communication device;
a second antenna radiating structure disposed within the housing of the wireless communication device;
a cover accessory removably attached to the housing of the wireless communication device, wherein the cover accessory overlaps with a portion of the housing;
characterized in that the antenna system further comprises;
three conductive elements each embedded within a volume of the cover accessory,at least one active component embedded within the volume of the cover accessory,wherein each of the three conductive elements is positioned to be in proximity with at least one of the first and second antenna radiating structures when the cover accessory is attached to the housing of the wireless communication device; and
wherein the at least one active component is coupled to at least one of the three conductive elements, the at least one active component is configured to vary a reactance of the at least one conductive element for tuning a response of the antenna system.

Abstract
An antenna system is integrated into a cover or accessory and adapted to couple to an antenna in a host device to improve transmission and reception of signals. The antenna system can be passive or active, with the active antenna system designed to amplify coupled signals on the integrated antenna elements in the cover or accessory. Single or multiple frequency bands can be improved with the integrated antenna system, and multiple antennas in the host device can be coupled to and improved. The antenna system can couple to the existing antennas in the host device by capacitive coupling, i.e. no physical contact required, or a connector can be designed into the cover or accessory containing the integrated antenna system that makes contact to electrical ground of the host device or power supply signals or other control signals.
