Abstract

We present the design steps of a coaxial dipole antenna for telemetry applications under extreme conditions of accelerations and centrifugal forces. Both, electromagnetic and mechanical designs are explained, as well as performance compromises that have to be made between both domains. The experimental results are given in the following part of the article, before some details on the instrumented firings and the receiving station; at last a few examples of projectiles equipped with such antennas are presented.
