This paper presents a metamaterial approach based ultra-wideband patch antenna using a different split-ring resonator structure. The proposed split-ring resonator is constructed on a 0.43mm thick RT Duroid substrate above a partly covered ground plane. The radiating element comprises of a rectangular geometry with arc-shaped structures at the shorter edges, with an overall dimension of 39x30 mm2. The proposed antenna provides a much favorable radiation pattern with a very efficient impedance matching across a wide bandwidth of 3-44 GHz, making it highly suitable for its operation at and beyond ultra-wideband applications and 5G communications. This paper discusses the antenna's design and the parametrical studies performed using available simulation tools. © 2018 IEEE.
