Singular Integral Formulations for Electrodynamic Analysis of Metamaterial-Inspired Antenna Array

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Analysis of Metamaterial Based Microstrip Array Antenna

An Efficient Metamaterial- Inspired Electrically-small Antenna

This article presents an inexpensive, efficient, and electrically-small antenna design that is based on a metamaterial-inspired structure driven by an electrically-small semi-circular loop antenna, which is coaxially-fed through a finite ground plane. The proposed antenna system is linearly scalable over a wide frequency spectrum. The design details and radiation characteristics of the antenna ...

Compact Semi-Circular Metamaterial-Inspired Dual-Band Antenna

In this study, a compact semi-circular metamaterial-inspired dual-band antenna is presented. The total antenna size is 0.22 o × 0.19 o × 0.02 o. Simulation results show dual-band operation with an impedance bandwidth of 2.7% for first band (resonant at 4.1 GHz) and 25.7% for second band (resonant at 6.15 GHz). The proposed compact metamaterialinspired antenna shows monopole-like radiation patte...

Convergence analysis of product integration method for nonlinear weakly singular Volterra-Fredholm integral equations

In this paper, we studied the numerical solution of nonlinear weakly singular Volterra-Fredholm integral equations by using the product integration method. Also, we shall study the convergence behavior of a fully discrete version of a product integration method for numerical solution of the nonlinear Volterra-Fredholm integral equations. The reliability and efficiency of the proposed scheme are...
