5503 Electric Field Generator

The Model 5503 top plate consists of four separate tube conductors that are connected in parallel at the feed and load ends. This four-wire transmission line acts as a plate conductor at frequencies up to 30 MHz. A vertical, quasi-static TEM mode electric field is produced between the four-wire system and the ground plane of a semi-anechoic chamber. The width-to-height ratio of the "four-wire plate" is designed for an impedance match to a 50 system without an input transformer.

An external forced-air-cooled load is used to terminate the Model 5503. The cooling system maintains proper operating temperature and is monitored by a temperature sensor. The load housing is connected to a plate in the chamber floor. A pulley systems allows users to manually adjust the height to accommodate various equipment under test (EUT) sizes. The E-field generator is easy to assemble and disassemble, and can be removed from the chamber when needed.
