In this paper, we present a novel antenna design based on metamaterial properties that operates in the millimeter wave regime. This design resembles the center of a flower with its petals, and thus we refer to it as a “Flower Metamaterial Antenna”. Unlike classic and traditional antennas, th...
Antenna design has evolved from bulkier to small portable designs but there is a need for smarter antenna design using machine learning algorithms that can meet today’s high growing demand for smart and fast devices. Here in this research, main focus is
Underneath this silicon layer is where an open-ended microstrip feedline is located which is used to excite the antenna. The feed mechanism is based on the coupling of the electromagnetic energy from the bottom silicon layer to the top circular patches through the cavity. To suppress surface ...
A compact dual wideband metamaterial antenna designed for wearable application is presented in this communication. A metamaterial resonator structure that
3.1. Single antenna design Fig. 9(a) and (b) shows the design of a single antenna using an affordable 0.22λ0× 0.34λ0× 0.02λ0 FR-4 epoxy substrate with a layer thickness of 1.6 mm, Ɛr = 4.4, and tan δ = 0.02. The antenna element is stimulated by a microstrip feedline,...
Fig. 2. Schematic with pyramids to illustrate the two foundations by design (i.e., topology optimisation, structural design, and a future perspective for ML-based design) and fabrication (i.e., material extrusion, inkjet printing, vat photo-polymerisation, etc., and a future perspective for ...
Metamaterial approach allows introducing additional design flexibility as compared with conventional approaches. For example, high-gain antenna design23, scattering suppression devices24,25, resonators for radiation efficiency enhancement26, hyperbolic metamaterial-based antennae27,28, and several others ...
This is because metamaterial-based antennas increase the radiated power of the antenna itself. Since metamaterials are able to exhibit negative magnetic permeability, properties such as (1) high directivity, and (2) tunable operational frequency. Furthermore, metamaterial antennas provide ultimate ...
The near field directivity factor, radiation efficiency with a breast model and coupling efficiency are computed to proof the antenna suitability for UWB-based MIS application. 2. Unit Cell Design Architecture The design view of proposed planar-square, left-handed, metamaterial SRR unit cell is ...
