  • High power ultra broadband antenna
    Patent number: 5479180
    Abstract: A hybrid antenna in which the flared end of a parallel plate of a transmion line is coupled to a frequency independent antenna so as to take the place of the higher frequency radiating portion of the antenna.

  • High T.sub.c superconducting microstrip phase shifter having tapered optical beam pattern regions
    Patent number: 5385883
    Abstract: The present invention is a superconducting opto-electronic phase shifter which is achieved by illuminating a superconducting microstrip line, which is fabricated on a dielectric substrate, with an optical beam of a predetermined intensity and shape. Because the superconducting microstrip will exhibit a local surface resistance when and where illuminated, the microstrip line will be artificially narrowed thereby producing a phase shift. This occurs because as the width of a superconducting microstrip line narrows the velocity of the carder signal increases. Therefore, if the illumination of the superconducting microstrip line causes a local surface resistance, then the surface impedance of the microstrip line is increased causing the effective width of the microstrip line to decrease. Hence, the artificial decrease in the width of the microstrip will cause the phase of the carrier signal to shift.
