Inductor or antenna arrangement with integral series resonating capacitors

Abstract

An improved inductor arrangement suitable for a wide variety of applications, but particularly advantageous for use in the design of ferrite antenna structures intended to operate at the relatively higher frequencies. The disclosed inductor arrangement includes a spiral inductor or coil divided into a plurality of wire segments, respective pairs of which are interconnected by individual capacitance elements to form a plurality of series-resonant circuits at a particular frequency or range of interest. The capacitance elements may be provided in the form of discreet components or by a suitable electro-deposition process in the interests of further optimizing size factor. The number of individual wire segments and resonating capacitance elements may be selected to provide a given terminal impedance for the inductor arrangement within a certain limited design range.
