Abstract

In this paper, a method to combine MATLAB-based optimization with a 3D electromagnetic simulator is described. The work-flow is presented using five main files (.m,.text,.bas,.sig and.rd1), which are required to establish the connection between the two software systems. Speed constrained particle swarm optimization (SMPSO) algorithm was implemented in MATLAB, which utilized the transient 3D simulator of CST Microwave Studio to carry out iterative full-wave analyses during the optimization process. As a design example, this customized optimization method was then employed to maximize the directivity-bandwidth product (DBP) of a mono-slab resonant cavity antenna (RCA). This optimization yielded a compact RCA, with a peak directivity of 21dBi and an extremely large directivity-bandwdith of 56%. The DBP of this optimized RCA is around 6500 and its total area is only 5.6λ2 0.
