Design of Wideband Slot Antennas By Using Combined Characteristic Modes

This paper proposes two methods to design wideband slot antennas. With the analysis of the combined characteristic modes, it is found that by loading two slot stubs or introducing a parasitic ring slot, a new mode can be generated, and hence, the bandwidth of the ring slot antenna can be enhanced owing to dual mode radiation.
