Abstract

An efficient procedure for the pre-design of circumferential circularly-polarized cylindrical microstrip arrays, based on the electric surface current model, is the focus of this work. Its major achievement is cutting the time to pre-design the patch dimensions down to less than one-tenth of what it takes in a 3D electromagnetic simulator, such as the HFSS, running on high-performance workstations. As a result, the array design procedure can be completed faster and more effectively.
