Thanks again,
One thing I didn't do I could have done to determine the resonant frequency of the 1/4 wave stub is to have frequency sweeped the probe I built using the RF signal generator and watch the peak response on a spectrum analyzer a few inches away on max hold receiving the signal to...
Thanks for your answer, seems the little "monopole' 1/4 inch piece of copper protruding out of the end of a length of coax was not close to resonant at 14 GHz because I measured two to three dB less signal level than there should have been at 1.5 inches away from the transmit antenna/stub...
Thanks, we looked for someone who had a probe and ended up having someone from another area fly in to take the measurements using a broad band EMF probe which worked fine before leaving on their trip here but would not properly zero once they began using it here. Regardless, the Ku band RF...
rf signal dbm to mw/cm2
Thank you very much, this information has been helpful. Can you also help me understand how you arrived at the level I should see for 10 mw per cm2? I would like to study this further. I have been in RF since high school, now over 50 years old but never had to calculate...
emi homemade euiqpment
Hi, I'm in Afghanistan and working with the US Army where we have some concerns the EMF field intensity at Ku-band 14 GHz might be too high for some people working near a parabolic antenna. I have a good HP 4407B spectrum analyzer to work with but do not have a EMI or EMF...
