<p>An antenna used as voltage and power source is designed to operate with arbitrary load, or front end, the antenna has one or more loading bars (950) that are placed adjacent to the elements (400) of the antenna at a spacing distance (940). The real part of the antenna input impedance is changed by adjusting the loading bar length (920), width, and/or spacing distance (940) and/or the number of loading bars (950). These changes are implemented to reduce the real part of the antenna input impedance to reduce the real part of the antenna input impedance to make it small enough to develop an adequate voltage, Vp, to operate the front end and connected circuitry, one or more stubs (980) is added to one or more of the antenna elements. The stubs (980) act as two-conductor transmission line and are terminated either in a short-circuit or open-circuit.</p> |
