Abstract :
In order to achieve multi-frequency operation from square ring antennas, two or more square rings are stacked and electromagnetically excited by a feed line located outside the bottom ring. The separation between rings is kept very small so that, the feed line can excite them all, and the overall height remains small. The number of rings is the same as the resonances in this configuration.
