A Simple Linear-Type Negative Permittivity Metamaterials Substrate Microstrip Patch Antenna

Abstract

A microstrip patch antenna (MPA) loaded with linear-type negative permittivity metamaterials (NPMMs) is designed. The simple linear-type metamaterials have negative permittivity at 1–10 GHz. Four groups of antennas at different frequency bands are simulated in order to study the effect of linear-type NPMMs on MPA. The antennas working at 5.0 GHz are processed and measured. The measured results illustrate that the gain is enhanced by 2.12 dB, the H-plane half-power beam width (HPBW) is converged by 14°, and the effective area is increased by 62.5%. It can be concluded from the simulation and measurements that the linear-type metamaterials loaded on the substrate of MAP can suppress surface waves and increase forward radiation well.

Unorthodox technique in sensing with the metamaterial-based resonator sensor at millimetre frequencies

“…Moreover, the permittivity of the structure is found to be near zero at the resonance frequency and it crosses zero point at 31.94 GHz frequency. This phenomenon of achieving permittivity negative and/or permeability negative is the interesting characteristic of metamaterial, causes the bandwidth of resonance narrow, which helps in characterising the materials with small changes in dielectric properties [22].…”

Artificial Magnetic Conductor as Planar Antenna for 5G Evolution

“…The planar configuration has a physical benefit which contribute to the compact system integration. The classical patch antenna has been incorporated into the concentric configuration of the two-layer-ringbased metamaterial, but the lateral size increases [15]. For a band above 6 GHz , the planar aperture antenna design has been introduced using a substrate integrated waveguide (SIW) structure based on a periodic groove surface to support the 5G band (around 10 GHz), however the complex layerbased composition is considered [16].…”

Design & Implementation of a Meta-Material Based Ultra-Wide Band Microstrip Patch Antenna for Vehicular Communication

“…In terms of bandwidth, gain, and e ciency, this antenna performed very well. Simple linear-type negative permittivity metamaterial substrate microstrip patch antenna with wideband operation and good radiation e ciency was presented by Hui et al [25]. Hossain et al [26] proposed a triple-band microwave metamaterial absorber, employing double E-shaped symmetric split ring resonators, primarily designed for EMI shielding and stealth applications.…”
