A single wire of length L = 2.5 m is parallel to a ground plane and 10 cm above it. The wire carries a sinusoidal current with amplitude I1 = 17 mA at the frequency f = 400 MHz. An antenna is oriented parallel to the wire, located at a distance d from the ground plane, and is connected to a spectrum analyzer. You are asked to:

• Sketch the system

• Compute the maximum radiated field at a distance d = 10 m away from the ground plane

• Assuming an antenna factor of 17 dBm−1 , compute the voltage read by the spectrum analyzer
