Calculating the voltage at the load of a reciving antenna

Hello,
if I have an antenna placed at an incident wave with the power density W[W/m²] and the antenna impedance Z_A and load impedance Z_L,
how can I calculate the voltage over the load Z_L?

hello flanello

why not refer to equations in the text, balanis

Maximum power delivered to the load= incident power density*effective aperture.

and then equations are fairly explained in the text.i assume you might have gone through them,?
