ABSTRACT:
A low profile electric field sensor is arranged to sense electric field potentials with respect to a local ground plane. The sensor includes an antenna in a generally planar format with a major dimension extending generally parallel to the local ground plane. To maintain signal to noise ratio, while at the same time minimizing the height of the antenna so as to provide a low profile, the antenna is coupled to a charge amplifier. The charge amplifier comprises an operational amplifier, preferably with a capacitor feedback between output and an inverting input, and the antenna is conductively connected to the inverting input.
