Title: David Sall: Innovator in Reflectarray Antenna Systems
Introduction
David Sall is a notable inventor based in Owings Mills, MD (US). He has made significant contributions to the field of antenna technology, holding a total of 3 patents. His work primarily focuses on reflectarray antenna systems, which are crucial for modern wireless communication.
Latest Patents
One of his latest patents is the "Reflectarray Antenna System." This innovative system includes an antenna feed designed to transmit and receive wireless signals across a specific frequency band. The reflector features a reflectarray composed of multiple elements, each containing a dipole element. Notably, some of these dipole elements incorporate both crossed-dipole and looped-dipole portions. This configuration allows the reflectarray elements to selectively phase-delay the wireless signal, enabling it to be transmitted as a coherent beam.
Another significant patent is the "Wideband Reflectarray Using Electrically Re-Focusable Phased Array Feed." This planar reflectarray system enhances bandwidth by utilizing a tunable feed array that adjusts in both amplitude and phase. This adjustment compensates for aberrations, allowing for feed re-focusing and field matching. The active tuning technique modestly increases the feed array's size while effectively correcting de-focusing issues when operating at frequencies away from the tuned center frequency.
