This presentation will discuss the key challenges in the virtual prototyping of body worn antennas, describing how CST MICROWAVE STUDIO can be used to construct realistic flexible and conformal geometries, and how these can be studied and optimized in the context of their body-centric environment. The design of these antennas is thus challenging, and numerical simulation is an indispensable tool for the antenna engineer. But the antenna operates in a particularly challenging environment, in close proximity to the human body, and its performance may be affected by deformation, e.g. The antenna is the crucial enabling component which allows communication between sensors, and with other off-body systems (e.g. Wireless body area networks are an increasingly important area of research and show great promise for monitoring and communication in diverse application areas such as healthcare, public safety and defence. In this presentation we will look at how some of these applications of metamaterial based structures are modelled and simulated using the relevant solver technologies within CST STUDIO SUITE®. Metamaterial-inspired antenna design has produced reflex-cavity antennas with low-profile, high gain, beam steering and frequency agility.
For this purpose, Rectangular microstrip patch antenna loaded with metamaterial structure has been proposed for improving the bandwidth by using CST MICROWAVE STUDIO in this paper. The metamaterial-based waveguide structures, such as composite right/left-handed (CRLH) structures, have led to interesting applications of waveguide miniaturization and novel coupler design. In this work, The drawback of Patch Antenna was impedance bandwidth. Some recent industrial applications have seen metamaterial transmission lines being used in broadband filters, multiband components, dual-band tags for UHF-RFID and sensors. The exotic properties of these metamaterials include negative or low values of permittivity, permeability and refractive index, allowing engineers to manipulate the material’s intrinsic parameters to control the propagation of electromagnetic waves. The subject of metamaterials has rapidly grown over the past few years from a hot topic of academic research to a field with interesting and novel industrial applications. In addition to its market and technology leading time domain solver featuring the PERFECT BOUNDARY APPROXIMATION (PBA)®, CST MWS also included modules based on numerous different methods including finite element method (FEM), method of moments (MoM), multilevel fast multipole method (MLFMM) and shooting boundary ray (SBR), each offering distinct advantages in their own domains.In CST's Complete Technology for 3D EM simulation approach, the seamless integration of the solvers into one user interface enables the easy selection of the most appropriate solver for a given problem class, delivering improved simulation performance and unprecedented simulation reliability through cross verification. Numerical techniques in CST for MW and RF applicationsĬST MICROWAVE STUDIO ® (CST MWS) offers the choice of multiple powerful solver modules. The following topics will discussed during this presentationġ.
