Abstract
This paper presents a novel metasurface-based aperture-coupled antenna for millimeterwave (mm-wave) wireless communication applications. The proposed antenna design is composed of an array of metasurface resonators, which consists of modified dipole elements, a ground plane with a rectangular slot, which is sandwiched between two dielectric substrates, and a 50Ω microstrip feeding line. The introduction of a metasurface array can address the narrower bandwidth issue of the patch antenna and improve its impedance bandwidth as well as antenna gain. From the simulations, it is noted that the proposed antenna offers a wide impedance bandwidth of 4.56 GHz, ranging from 25.5 to 30.06 GHz. The antenna efficiency is noted to be >95% in the operating bandwidth, while the antenna gain increases linearly with the increase in the frequency. On the basis of the results, it is worth mentioning that the proposed antenna is a suitable candidate for mm -wave wireless communication applications.
