Effects of Electron/Ion Particle Spray on Antennae

  1. Nov 3, 2013 #1
    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
