Assume the power transmitted is p(W), the distance between the transmitter a
nd the receiver is r(m), then the power flux density at the location of the
receiver is
S=p/[4*3.14*r^2] (W/m^2).
Assume the effective length of the antenna of the receiver
is l(m). My question is how to caculate the voltage v(V)generated in the ant
enna? Is the following equation correct?
(v/l)^2/367=S=p/[4*3.14*r^2]
