Latest Patents

Francis Carr holds a patent for a "Miniature antenna with separate sequentially wound windings." This invention is particularly useful for portable radios, pocket pager receivers, and similar devices. The design features a plurality of sequentially wound windings located on a ferrite core, with each winding connected in series with a capacitor. The resulting series circuits are connected in parallel with each other, allowing for improved performance. The resonant frequency of each series circuit is approximately 80% to 90% of the receive frequency, which optimizes the antenna's functionality. An external tuning capacitance resonates with the net inductance of the antenna at the receive frequency, ensuring low hand effect while maintaining output EMF.
