This paper presents the resonance transmission of a small, narrow slot in a conducting screen with two parallel wires. When a plane wave excites the slot, the aperture magnetic current is controlled by the wires connected across the slot. Parallel-wire-loaded slot resonance can occur, which is known as a transmission resonance or extraordinary transmission. In this case, the electromagnetic power transmitted through the slot with the wires is much larger than that when the wires are not present. The results show that the wires result in the maximum power transmission (resonance transmission or extraordinary transmission). The resonant frequency of a 3-cm slotted structure can be reduced from 4.56 GHz to various desired frequencies by adding the wires.
