#askleo explain what this means in simpler terms:

a closed oscillating circuit does not radiate if the current of high frequency flowing in it is such that the current flows in all its parts in the same direction at the same time, while the same circuit does radiate radio waves into the aether if the current is made to flow in opposite directions at the same time in different parts of the circuit and thus creating loops (antinodes) of potential along the wires of the circuit.
