The simplist route to measuring microwave field strength is a spectrum
analyzer and a standard-gain horn antenna.
You can then convert from the dBm measurement of the spectrum analyzer
to dBuV/m by using the calculated gain of the horn antenna, accounting
for the loss in any interconnecting coaxial cables/waveguides.
You can even build your own standard gain antenna, see http://www.w1ghz.org.
Or try eBay.

Hi,

From my search, I found two companies that manufacture field strength

meters: Potomac Instruments and Z-Technology. I was wondering if there
are others. It seems that these companies do not go past 3Ghz.

We are interested in measuring field strength all the way up to 18Ghz.
Does anyone know of any manufacturers that do this?

An alternative would be to use spectrum analyzers with the right
antenna, but I'm not aware of any spectrum analyzer that measure field
strength. From my lab experience, we were mostly dealing with dBm. I
did not see any option for V/m. Plus, they are very expensive. Thanks!
