ADMITTANCE, ISOLATION, AND RADIATION PATTERNS OF RECTANGULAR SLOT ANTENNAS IN THE PRESENCE OF A SIMULATED REENTRY SHEATH

Abstract

The admittance, isolation, and element radiation patterns of reduced- height rectangular slot antennas in a plasma-clad ground plane were measured and compared with theoretical predictions. The plasma sheath simulates the electromagnetic properties of a high-altitude boundary layer and is produced by pulsed electron beam emission from the ground plane in the presence of a low-pressure gas.
