Latest Patents

One of Steven J Franke's notable patents is the "Continuous phase shifter for a phased array hyperthermia system." This invention provides a continuous microstrip phase shifter suitable for use in a phased array microwave hyperthermia system operating at 915 MHz. The phase shifter utilizes a three dB quadrature hybrid coupler in conjunction with microstrip lines to change the phase of a transmitted wave. The phase change is introduced through the reflection ports of the coupler, which are loaded with identical parallel resonant circuits. An abrupt junction varactor capacitance in parallel with a distributed inductance forms a voltage-tunable resonant circuit. The resonant element values are chosen to give a specified continuous phase variation with minimum transmission loss, accomplished without additional microwave circuit elements.
