Abstract

An antenna coupled to a wireless communication device is comprised of a conductive component, such as a series of conductive elements, that forms a conductor if placed under a threshold force. The conductor is coupled to the wireless communication device so that the wireless communication device is capable of communicating at an operating frequency defined by the length and construction of the conductor. By communicating using the conductor as an antenna, the wireless communication device may provide an indication of force to an interrogation reader. Furthermore, a conductive support element, such as a tuning ring, may be used for communication as well as coupling the conductive component to the wireless communication device. Multiple conductive components may be coupled to the wireless communication device for communicating at multiple frequencies if placed under multiple threshold forces.
