Title: The Innovative Contributions of Daniel Davis
Introduction
Daniel Davis is a notable inventor based in Baltimore, MD (US), recognized for his significant contributions to antenna technology. With a total of 5 patents, Davis has made strides in developing advanced systems for space applications.
Latest Patents
One of his latest patents is the "Limited Field of View Antenna for Space Borne Applications." This invention features a hybrid parabolic reflector phased array antenna system that is stowable in a space vehicle and deployable in space. The design includes a large torus that acts as a support structure for multiple small reflector cells, known as super elements. Each super element contains its own reflector and an array of feed elements. The torus supports a stretched reflector mesh and backup catenary wires, which help maintain the exact paraboloid shape of the reflector surface. The super elements can incrementally scan the beam by selecting groups of feed elements, utilizing time delay phase control for precise steering.
Another significant patent is the "Hexagonal Array Antenna for Limited Scan Spatial Applications." This invention consists of ninety-one elements arranged in a phased array of five concentric hexagonal rings around a center element. The design forms nineteen hexagonal sub-arrays, each containing seven dipole elements. A digital beam former is employed to produce the necessary amplitudes and phases to steer the antenna and generate overlapping beams.
