This problem is about finding the effective height of an antenna (Antenna A) using measurements.

You are given the following information about antenna A: When A is transmitting, its radiated far-field expression is given by:

Ea(z) = E0 e-jkz(x + jy)/sqrt(2)     V/m

When Antenna A is in the receiving mode and in presence of the incident plane wave: E1(z) = y*ejkz         V/m

the antenna open circuit voltage is measured to be V1 = 4ej45 V

Now consider the plane wave E2(z) = 10( 2x + yej90) ejkz         V/m

Illuminating Antenna A. Find the measured open circuit voltage V2.

(Hint: you need to first find the effective aperture or height of the antenna A using E1 and V1)
