Hello Marinos,
There have been several schematics using such technics over the last 20
years. Most of them use a seperate short antenna, feeding the signal pase
shifted into a combiner which combines the main Antenna Signal with the
phases shifted extra antenna signal. This construction can

Hi Peter,
Would this type of noise canceler not work on white noise also ?

The simplest answer is no. White noise typically arrives from random
directions, with random phases, random polarizations, etc. etc. etc. and
are usually from thermal

That depends a lot on the source of the noise, broadband (white) or
otherwise. These circuits depend upon a second antenna picking up the noise
better than the signal. Then the signal from the noise antenna
