Effects of circuit geometry on the electromagnetic radiations of small circuits

With algebra and trigonometry it is shown that the electromagnetic radiations of small circuits are highly dependent on circuit-current path geometry and the location of the current source in that path. The radiation of small circuits and small loop antennas can best be approximated by not neglecting the time required for their currents to propagate, no matter how small they may be. The assumption made here is that the current of a current element has the same amplitude and phase over its length, but the phases of the currents of neighbouring current elements differ by the time required for the current to propagate from the center of one to the center of the other. Based on that approximation it is seen that the radiations of small circuits can best be minimized by placing their forward and return current paths as close together as possible starting at the points where those paths leave the source of the current.
