Introduction

F William Hopwood is a notable inventor based in Severna Park, MD (US). He has made significant contributions to the field of antenna technology, holding two patents that showcase his innovative approach to electronic systems.

Latest Patents

One of his latest patents is an antenna system using time delays with mercury wetted switches. This invention features an electronically steerable antenna array that includes time delay units connected to individual antenna elements. These units are designed to time delay a microwave signal to and/or from the antenna elements. Each time delay unit incorporates small mercury wetted switches that control signal flow via a time delay path or a bypass path. The mercury wetted switch itself consists of spaced apart conductors with a high resistivity gate member in between. First and second mercury droplets are connected to the ends of the conductors. When a control signal is applied to the gate member, the mercury droplets are drawn to it, establishing an electrical connection between the conductors to close the switch. Upon removal of the control signal, the mercury droplets separate and revert to their initial droplet form, thus opening the switch.
