<p>The invention is a miniature antenna useful for portable radios, pocket pager receivers, etc. A plurality of sequentially wound windings is located on a ferrite core, each winding being connected in series with a capacitor. The resulting series circuits are connected in parallel with each other. Preferably the resonant frequency of each series circuit is approximately 80% to 90% of a receive frequency. An external tuning capacitance resonates with the net inductance of the antenna at the receive frequency. The antenna exhibits low hand effect while maintaining output EMF.</p> |
