Latest Patents

One of his latest patents is titled "Planar array antenna having radome over protruding antenna elements." This invention features a subarray of a planar array antenna with a ground plane that has both a rear and front face. The radiating elements protrude forward of the front face and are physically mounted to the ground plane. The design includes circuit elements that are electrically coupled to the radiating elements and positioned rearward of the ground plane's rear face. A dielectric radome is supported on the ground plane, creating a continuous surface that seals around the radiating elements, ensuring environmental protection.

Another significant patent is the "Mutual coupling method for calibrating a phased array." This method involves performing initial measurements of array antenna elements to ensure that calibration measurements remain within the linear dynamic range of the receive elements. It includes deriving calibration coefficients from direct measurements of forced out-of-phase conditions and detecting deep nulls through adjustments of amplitude and phase settings across a range of frequencies.
