Enhancement of loop antenna reception using glow discharge plasma core

Experimental results on the behavior of air glow dc discharge column radio frequency antenna are presented. The effect of the discharge conditions on the loop antenna gain at five radio frequencies of 9.3, 10.0, 13.6, 16.5, and 19.1 MHz are studied. Increases in the loop antenna gain of up to 5 dB are observed. The increase in gain is observed to rise with increased plasma density at the onset of the discharge approaching a saturation limit as the plasma density is increased further.
