SLOTTED CYLINDER ANTENNAS FOR RADIOSONDE SET AN/DMQ-6
Abstract
Rocket-borne Radiosonde Set AN/DMQ-6, adapted from a balloon-borne equipment to gather the high-altitude wind and temperature data needed for missile design and evaluation, requires a compact, omnidirectional antenna with good axial coverage to permit tracking of the rocket nose cone on descent as well as ascent. A helical slotted cylinder antenna, compact enough to fit into the nose cone of the ARCAS rocket and with operation in the 1660 mc to 1700 mc frequency range, was developed to meet this requirement. The helical, center-fed slot was cut in a cylinder. A second requirement, arising from the need to use the entire upper portion of the nose cone for sensory equipment, was satisfied by the development of a circumferentially slotted cylinder antenna. This antenna consisted of a cylinder around which four center-fed circumferential slots were symmetrically placed. Both antennas proved satisfactory in engineering flight tests.
