Efficient Design Optimization and Variability Analysis of Defected Ground Structure Filters Using Metamodels Vrije Universiteit Brussel
Microstrip filters are widely used in modern microwave communication systems such as Wi-Fi, 5G and satellite navigation. This increasingly broad range of applications implies that the frequency spectrum becomes more and more crowded, resulting in more demanding filter specifications. To meet these design specifications, computationally expensive electromagnetic simulations are often used. To speed up the filter design flow, we introduced metamodels ...
