Experimental Simulated Plasma Results on Base-Mounted Antennas
Abstract
A study is made of the performance of base-mounted antennas on a reentry nose cone. The effects of a simulated overdense plasma on flush mounted cavities and protruding J-slot antennas (located respectively in and on a cone base) have been investigated. Changes in radiation patterns for various distances of simulated overdense plasma extending backward from the rim of the cone base are shown, as are Smith chart presentations of the input impedance. Additionally, bandwidth data and coupling data are also presented for both types of antennas. Finally, the voltage breakdown levels for the J-slot, both air filled and dielectric filled, were determined.
