Note that the phase of the field varies with fr/c, corresponding to the delay caused by the radiation traveling at the speed of light. We are not concerned here with actually finding the radiation pattern for

The interconnection between elements, called the feed network, can provide fixed phase to each element or can form a phased array. In optimum and adaptive beamforming, the phases (and usually the amplitudes) of the feed network are adjusted to optimize the received signal.
