Study of multilayer microstrip antennas with radiating elements of various geometry

Abstract

A study of multilayer microstrip antennas fed by coaxial probe or microstrip line is presented. The method developed is applicable to structures with stacked or offset radiating elements of various shapes including rectangles, discs and triangles. Theoretical and experimental results of input impedance are given for the different structures. Radiation information is presented and the relative merits of different structures are discussed.
