Latest Patents

Mantele’s patent, “Non-dispersive variable phase shifter and variable length transmission,” describes a varactor-controlled phase shifter designed to maintain substantially equal phase velocities across frequencies. Its phase shift can be adjusted with an external control voltage and varies linearly with frequency. The device can also function as a variable-length transmission line, including for frequency-selective impedance matching.

His patent, “Fiber-optic feed network using series/parallel connected light emitting,” presents a corporate feed network using light-emitting optoelectronic components, such as laser diodes, connected in strings. Optical fibers link the components to systems such as active phased-array antennas. The design uses series and parallel connections to distribute RF, microwave, millimeter-wave, digital, and pulse-modulated optical signals while supporting wideband impedance matching.
