A wideband stacked patch antenna is presented in this paper. The proposed antenna consists of a stacked structure and rectangular shell under the finite ground of the antenna. A 91.7% bandwidth is obtained by carefully arranging the relative permittivity of the substrates of the upper and lower layer. The proposed antenna is suitable for the modern communication systems.
In this paper a newly designed metasurface (MS) loaded miniaturized antenna is proposed and simulated. The double layered MS loaded with complementary split ring resonators (CSRRs) acts as the ground plane for a planar feeding monopole antenna. The antenna has a compact footprint of 0.11λ02 and a thickness of 0.07 λ0. The simulation results show that a wide −10 dB S11 bandwidth of 9% is realized....
In this paper, we present both the theory and design of an anisotropic metamaterial lens for antenna applications. This type of lens requires simple effective medium tensor parameters to achieve highly-directive radiated beams, which differs from more conventional isotropic zero-index metamaterial lenses. Making use of the less dispersive low permittivity and/or permeability band, the lens is promising...
