Abstract
The Finite-Difference Time-Domain (FDTD) technique is the most widely used computer method for tackling electromagnetic issues. The antenna’s broad operational band is 1.0 GHz to 4.5 GHz due to the textile material and radiation patch shape. The effect of the human body on the antenna is mathematically analyzed using a digital human model. The findings of the simulations and measurements in free space and on the human chest are quite similar. The research also discovered that the performance of the cloth antenna did not diminish in these conditions. Furthermore, the suggested technique addresses both lossless and general loss issues. Numerical experiments indicate the benefits of the proposed technique over traditional FDTD and state-of-the-art explicit and unconditionally stable FDTD methods. As a consequence, the creation of conductive fabric has turned into an exciting field of research. Using the FDTD technique to analyse the boundary conditions, the recommended design makes it feasible to achieve the transient mode utilized for the resonating frequencies of Transverse Magnetic (TM) and Transverse Electric (TE) modes. The computational analysis for input impedance matching is regarded to be below the boundary conditions for the current distribution when using the spectral-domain technique for linear and non-linear features. The various resonating frequencies to analysis from the 1.09 GHz to 4.5 GHz with the FDTD for the electric field and magnetic field is obtained from higher values to 80 and lowest value to 60. On resonant frequencies, radiation pattern features of the current electric field distribution, various antenna parameters are analysed and addressed.
