Reentry Plasma Attenuation for S-Band Telemetry Systems

Abstract

The performance of a slot telemetry antenna is analyzed, including the effects of an inhomogeneous plasma sheath on aperture admittance, radiation pattern distortion, antenna window absorption, reflection and absorption losses of the feed network, and total antenna gain. The change in broadside antenna gain induced by the reentry plasma sheath is compared with plane wave signal attenuation calculations. Various antenna matching conditions are evaluated for free-space and reentry-plasma conditions.
