摘要：

A novel computer-aided design (CAD) procedure for microstrip antennas is proposed in this letter. It is based on a previously developed analysis methodology that combines the finite element method (FEM), domain decomposition, and a technique called multipurpose admittance matrix. This method is reformulated in order to allow continuous geometry variations of conducting surfaces, making a 2D-FEM optimization process possible. Measured and numerical results for a practical broadband microstrip antenna design demonstrate its robustness and versatility.
