Abstract
A system for measuring a free space electric field includes an ultrahigh impedance antenna positioned in the electric field to generate a signal from the electric field. An amplifier having an input port is provided to amplify the signal. The amplifier generates an input bias current which combines with the signal to create an input potential at the input port. An electrical circuit connects the input port to a ground connection and includes at least one circuit element for controlling the input potential to stabilize the signal at the input port.
