High gain and efficiency dual-band antenna using meta-surface
This article presents a compact meta-surface (MS) based antenna with dual-band operation for 5G applications. The MS-based antenna consists of a layer of MSs on the top of a single-band microstrip patch antenna. The dual-band operation is achieved by adding the MS layer at a height of 0.089λ0, where λ0 is the free space wavelength at the lower resonant frequency. ... Read more
