Title: Andrew Rowser: Innovator in Active Antenna Systems
Introduction
Andrew Rowser is an accomplished inventor based in Kent, WA (US). He has made significant contributions to the field of antenna technology, holding a total of 2 patents. His work focuses on developing advanced active antenna systems that enhance communication capabilities.
Latest Patents
Rowser's latest patents include a broadband, high-gain, active antenna system. This innovative system operates with a bi-directive reception pattern in its standard configuration and can switch to a directive reception pattern across various octaves of the Radio Frequency (RF) spectrum when equipped with a tuned scatter-plate. The antenna probe element and amplifier subassembly demonstrate bi-directional directive properties akin to a standard fixed-length dipole. The addition of a scatter-plate allows for frequency-dependent directive modes, which can be tuned for optimal performance in specific RF frequency ranges.
Another notable patent is the miniature ultra-wideband active receiving antenna. This compact design utilizes high transconductance transistors arranged in a Cascode amplifier configuration. The invention aims to improve linearity and dynamic range while maintaining high input resistance and low noise levels. The gain of this antenna is primarily determined by the amplifying electronics, eliminating the need for increased directivity to achieve higher gain.
