Abstract
A radio frequency proximity reader has a base plate housing portion that has an essentially rectangular shape with first and second opposed major surfaces and a centrally located bore. A cylindrical housing portion having a concentrically placed bore is attached to the base plate and extends substantially perpendicular to the first major surface, with the bores of the housing portions being substantially aligned. A radio frequency antenna including a cylindrical ferrite core having at least one concentrically wound coil is concentrically located within the cylindrical housing portion. A light emitting diode and a piezo buzzer are provided within the cylindrical housing portion adjacent the second major surface of the base plate. A cable electronically connects the reader to remotely located signal processing circuits. The base plate may be attached to a wall, whereby the first surface abuts the wall. A rectangular cover attached to the base plate covers the second major surface of the base plate.
