High-Gain Wideband Metasurface Antenna With Low Profile
In this paper, a novel compact wideband and high-gain antenna based on metasurface is proposed. The antenna is an octagon with a side length of 32.3 mm and a height of 5.6 mm. The metasurface consists of two stacking layers, and both layers contain a 4×4 copper patch array. The antenna is...
