## Abstract The finite‐difference time‐domain (FDTD) method is used to model the response of microstrip patch antennas on magnetized ferrite substrates. The proposed FDTD model utilizes the auxiliary differential equation approach to represent the frequency dependent permeability tensor in the time

Abstract
This paper is concerned with the rigorous investigation of the radiation properties of a planar patch antenna on a photonic crystal substrate. Under the assumptions that the driving frequency of the antenna lies within the band gap of the photonic crystal substrate and that the crystal satisfies a symmetry condition, we prove that the power radiated into the substrate decays exponentially. To do this, we reduce the radiation problem to the study of the well‐posedness of a weakly singular integral equation on the patch antenna, and to the study of the asymptotic behaviour of the corresponding Green's function. We also provide a mathematical justification of the use of a photonic crystal substrate as a perfect mirror at any incidence angle. Copyright © 2001 John Wiley & Sons, Ltd.

## Abstract The goal of this work is to further investigate on the use of a truncated planar metallic periodic structure (grounded FSS‐based) to create new resonance frequencies in a patch antenna. The periodic structure is placed inside the microstrip patch antenna (between the metallic ground pla
A detailed characterization of the effects of antenna coating on the performance of cellular phones is presented. The FDTDbased simulations show that antenna coating facilitates the reduction of the antenna length without jeopardizing the radiation properties of the antenna. Howe¨er, the radiation e
