Effects of Electron/Ion Particle Spray on Antennae

Click For Summary
SUMMARY

The discussion centers on the effects of electron and ion particle sprays on a 300 MHz patch antenna. The user observed a significant voltage drop followed by a spike in signal, which correlates with the timing of the particle spray, despite the detected frequency being orders of magnitude lower than the antenna's calibration. This suggests that the particle spray may influence the antenna's performance, potentially introducing low-frequency signals. The environment includes small iron particles traveling at approximately 30 km/s, which may also contribute to the observed phenomena.

PREREQUISITES
  • Understanding of antenna theory and calibration, specifically for patch antennas.
  • Knowledge of electromagnetic theory, particularly the behavior of charged particles.
  • Familiarity with signal processing and frequency analysis techniques.
  • Experience with experimental setups involving particle sprays and their effects on electronic devices.
NEXT STEPS
  • Research the impact of charged particle interactions on antenna performance.
  • Explore methods for analyzing low-frequency signals in high-frequency systems.
  • Investigate the effects of environmental factors on antenna signal integrity.
  • Learn about advanced signal processing techniques to filter and interpret mixed frequency signals.
USEFUL FOR

Electronics engineers, antenna designers, researchers in electromagnetic theory, and anyone studying the effects of particle physics on communication systems.

I was wondering if an antenna could pick up some sort of signal if it was exposed to a spray of electrons or ions. For instance I have a patch antenna calibrated for 300 MHz. The patch antenna was placed in an environment where it could be getting sprayed by a wave of electrons followed by a wave of ions. In the antenna response I see a very strong signal voltage drop follow by a strong spike that is temporally correlated with when it would be getting sprayed, but the frequency of this signal is orders of magnitude below 300 MHz. Is this a possible effect of the particle spray, or is it more likely that something else is the cause of this low frequency signal showing up on a high frequency antenna. Any help would be GREATLY appreciated!

Is this something that is actually happening? If so, what kind of environment is your antenna located in?
 
The antenna is located near a target that is being impacted by small iron particles traveling around 30 km/s
