Latest Patents

Among his latest innovations, Yoshio Aoki has developed a high-frequency switch and an antenna device. The high-frequency switch comprises an input interface designed to receive high-frequency signals and an output interface to transmit these signals externally. A key feature is the reactance switch, which includes multiple reactance circuits connected in a cascade arrangement. Each circuit is tailored to create a common passband for the high-frequency signal, allowing at least one of them to be a variable reactance circuit, which adjusts its reactance based on an external control signal, thus modifying the passband accordingly.

In addition, Aoki has developed an antenna device that minimizes performance degradation even as the profile becomes lower. This device incorporates four FM band antenna elements and two AM band antenna elements positioned side by side on an antenna base. The synthesis circuits corresponding to each antenna element are strategically placed within the antenna's inner space. Each antenna element features a helically wound linear conductor and a planar conductor, ensuring omnidirectional performance in the horizontal plane.
