Chapter 8, Problem 8.39P

Two small loop antennas, each oriented in the $x-y$ plane, are centered at $\pm \lambda /2$ on the x-axis. They each have a 1.0-cm radius and are driven in phase by a 10.-mA current source at 500. MHz. Find and plot the radiation pattern at $\theta =\pi /2$ and determine the maximum time-averaged power density at a distance 100. m from the array.
