A RadioFrequencyGainPattern for modeling planar phased array antennas. The phased array model consists of many radiating elements. Each element is modeled as an
isotropic pattern. By modifying the excitation (amplitude and phase) of each element differently, a phased array antenna can electronically steer its maximum gain toward a
particular direction or main radiation axis. A phased array antenna not only can steer its maximum gain in a particular direction, but it can also steer nulls toward other
directions in an effort to prevent radiation to and from other directions. The act of altering each element's excitation is effectively accomplished through the assignment of
weights to each element. This set of weights for a particular direction is called a steering vector and each weight is a complex number.
