<p>Methods of forming electronic signal transmitting/receiving devices and electronic signal transmitting/receiving devices are described. In one implementation, integrated circuitry including transponder circuitry is provided and operatively coupled with an antenna to provide a transmitting/receiving circuit. A matrix material comprising suspension structure is formed and applied over at least a portion of the antenna, the suspension structure being selected to manipulate an operating characteristic of the transmitting/receiving circuit. According to a preferred aspect of the invention, the operating characteristic comprises an electrical length of the antenna and the application of the matrix material effectively increases the electrical length to resonate the antenna at a desired frequency. According to another preferred aspect of the invention, the suspension structure comprises calcium carbonate.</p> |
