In this paper, we applied the circuit synthesis theory of filters to the design of transmission-type metasurface cells and arbitrarily designed the amplitude and phase of the transmission and reflection by adjusting the resonant frequency and coupling coefficient. In addition, we successfully designed the phase of the unit cell by using the frequency conversion of filter theory. Moreover, we designed a refractive transmissiontype metasurface plate with a novel cell structure that reacts to both polarizations. The prototype operated at the desired refraction angle, confirming the design theory.
We have proposed a small antenna designed to radiate directly from AMC (AMC antenna). In this paper, the calculated results of two‐dimensional distribution of the mutual coupling and the correlation coefficient are discussed by the AMC antenna and a planar inverted‐F antenna (PIFA). Especially, the mutual coupling and the correlation coefficient of AMC antenna are measured.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
