Abstract: A nearfield/farfield transmission/reception antenna formed with a body of revolution having a somewhat saucer-like outside appearance. The body includes three main functional portions--a converter portion wherein farfield radiation is converted to "appear" like nearfield radiation and vice versa, a terminator portion which provides a constant-impedance termination for the converter portion, and a coupling-impedance transformer portion which matches the device to the impedance of a coaxial port in an external circuit. A ring-like driven element occupies an interface plane between the converter and terminator portions. Distributed on the outside curved surface of the body is a conductive electromagnetic/electrostatic shield.
