Resonant Behaviours of Microstrip Antenna in Multilayered Media: An Efficient Full-Wave Analysis

Abstract

Abstract-This paper presents an efficient analysis of a microstrip antenna in multilayered media using the method of moments (MoM). The general forms of spectral-domain Green's functions for multilayered media are converted into the spatial-domain Green's functions using the discrete complex image method (DCIM). With the spatial-domain Green's functions, the mixed potential integral equation (MPIE) is discretized in spatial domain, and the resultant system of equations is then solved using the biconjugate gradient (BCG) method. As applications, resonant frequencies of microstrip antennas in multilayered media are analysed. The numerical results show that the present method is an efficient and accurate scheme for analysing microstrip antennas in multilayered media.

Comparative Study of the Resonant Frequency of E-Plane and H-Plane Coupled Microstrip Patch Antennas

“…The resonant frequencies in the even and the odd resonance modes of half wave coupled and quarter wave coupled rectangular microstrip resonators were computed by Sharma and Bhatt [4]. Many authors [5][6][7][8][9][10][11] have investigated the effect of mutual coupling. But none of these works presents the comparative study for the resonant frequency of the E-plane coupled and H-plane coupled microstrip patch antennas.…”

A Polarization Compensation Approach Utilizing a Paraboloid Photonic-Crystal Structure for Crossed-Dipole Excited Reflector Antennas

“…The formation of the layers exhibits periodicity using dielectric materials that can be recognized as multilayer films printed on a bottom dielectric substrate [5,21,22]. The full-wave analysis of the printed conductors, consisting of multilayered array of patches in a stratified dielectric medium, has been proposed, but it is still computationally heavy [23][24][25][26]. The different mechanisms of energy re-distribution in the TE and TM modes may be used to make their ratio become smaller if the structure is designed properly because at high frequencies the radio waves have characteristics of propagation similar to ray optics.…”

Radiation Analysis of Large Antenna Array by Using Periodic Equivalence Principle Algorithm

“…In order to simulate the currents on the element and the coupling among different elements accurately, fullwave method is necessary. Common numerical methods to solve the problems of antenna arrays include method of moments (MOM) [5][6][7], finite element method (FEM) [8], and finite difference time domain (FDTD) [9,10]. MOM is based on integral equations.…”
