Abstract
A communication device includes a first FSS (Frequency Selective Surface) element, a second FSS element, a feeding radiation element, a first electron gun, and a first electron collector. The second FFS element is adjacent to the first FSS element. The feeding radiation element generates an electromagnetic signal. The electromagnetic signal is propagated by using the first FSS element and the second FSS element. The first electron gun transmits a first electron beam. The first electron collector receives the first electron beam. An antenna structure is formed by the first FSS element, the second FSS element, and the feeding radiation element. A coupling effect is induced between the first electron beam and the electromagnetic signal, such that the radiation energy of the electromagnetic signal is enhanced.
