Hello Group, A book I've been reading gives the Rayleigh criterion for farfield conditions based on antenna (or EUT max dimension) size as
dist for farfield conditions > 2*(max antenna dimension)^2/lambda When I look at this, it says that the required distance for far field conditions increases as the square of the dimensions of the antenna, which seems intuitive. What I found strange is that if you hold the antenna dimension constant, (ie for a given fixed antenna dimension) it predicts that the distance for farfield conditions will increase linearly with the frequency. That does not seem intuitive. Does anyone have a thought about how this works?
