Latest Patents

One of his latest patents is focused on scan compensation for array antennas on a curved surface. This invention features a low array antenna equipped with transmit/receive (T/R) modules that include digitally-controlled variable attenuators for both horizontal and vertical polarizations. The array is designed with a cylindrically curved surface that closely matches the shape of airborne vehicles or other structures. The elevation beamformer apparatus provides uniform and Bayliss/Taylor taper adjustments as the beam is scanned in elevation. This technology allows for low sidelobe far field sum patterns by adjusting the amplitude taper through the variable attenuator. Additionally, the T/R module is designed to combine distorted Bayliss difference patterns with compensated Taylor sum pattern outputs, ensuring high-quality, low sidelobe performance.

Another significant patent involves a patch radiator element with a microstrip balun circuit. This low-profile patch radiator is designed for use in array antennas and features a multilayer structure that includes a double-tuned impedance matching network and balun, along with a coaxial feed for linear polarization. A second embodiment of this invention enhances dual polarization operation, further increasing the frequency bandwidth of the patch radiator.
