Latest Patents

Gilhespy holds a patent for a "Scanned Antenna System." This invention comprises a feed horn illuminating a circular flat panel formed from a high impedance surface structure. By controlling the resonant frequencies of the individual elements of the array, a controlled phase shift profile is applied across the surface of the panel to an incident phase front spherically spreading from the feed antenna. This allows for the reflection of the wavefront in a particular direction or the imposition of a certain desired beam shape. The principles are reciprocal, enabling the creation of a receiving system or supporting simultaneous transmit and receive operations. The phase-controlled reflecting plate performs focusing to the feed and facilitates beam scanning or shaping. The active component at each array element affecting the resonant frequency is a single varactor tuning diode per element, which operates with negligible power dissipation. A further embodiment includes a transmissive panel with phase-shifting elements implemented in MEMS technology. Calibration techniques are also described to correct for non-systematic errors in the phase shifts on reflection, ensuring the integrity of the beam shape and pointing direction in practical environments.
