I built the circuit from the page below.

The I get 0v out when held near my wireless router, if
I put it near the microwave oven, the high input impedance
meter bounces up and down between 7mv and 80mv and
everything in between.

Don't treat the microwave oven as a "steady source" for RF. There is
usually a rotating "stirrer" in the waveguide entrance to the cooking
chamber. This is engineered to more evenly distribute the RF energy
about the cooking chamber -- eliminating (hopefully) hot and cold spots.

You may actually be seeing peaks and nulls as an artifact of this design.
