Abstract:

A quarter-wavelength ring antenna was developed to telemeter active fuzes in flight with a minimum modification to fuze or artillery round. Using principles of strip transmission line theory, general design criteria were established to maximize radiation efficiency within a fixed form factor. Electroplating and selective machining provided for economical, accurate production. Antenna field strength measurements verified expectations as to adequate radiation efficiency and a highly symmetric, ring-shaped pattern. This type antenna provides the ability, for the first time, to telemeter in-flight active fuzes without major shell modification.
