Abstract:In this paper, a slotted‐circle patch metasurface that can efficiently absorb electromagnetic (EM) waves in three different bands is proposed. Based on the fundamental resonance of a single circular patch, EM resonances are generated making slits in the circular patch leading to multi‐band operation. Simulation results show that the proposed structure can absorb signals in three different bands, namely at 8.10 GHz, 15.39 GHz, and 19.7 GHz with absorption peaks of 99.8%, 99.7%, and 99.8%, and absorption bandwid… Show more
