Abstract

A new periodic metallo-dielectric structure embedded in a high-dielectric-constant layer within a multilayer substrate configuration for a microstrip patch antenna is proposed and studied. The complete 2D periodic structure of the antenna's planar metallic elements is simulated using a finite-difference-based method. The impedance band-width and gain of the antenna are measured. The multiple-resonance structure proposed achieves much wider bandwidth, as compared to that of the single multilayer microstrip antenna. (C) 2005 Wiley Periodicals, Inc.
