Abstract

Many real-world electromagnetic design problems are difficult, and their optimisation requires the algorithm to manipulate diverse types of variables and multiple constraints. The cross-entropy (CE) method is a flexible and fast optimisation technique that can be used for optimisation of electromagnetic design problems with mixed variables and multiple constraints. The paper demonstrates the application of the CE method to the design of all-dielectric compact resonant cavity antennas with high gain and wide 3-dB directivity bandwidth and microstrip lowpass filters with high selectivity and wide rejection bandwidth. Both designs incorporate the requirement of fitting the allocated space. The optimised aforementioned designs show further improvement in the performance as compared to the original ones.
