“…The second microwave example is a zigzag narrow bandpass filter (see Figure 8) based on the design proposed in [58]. The filter is defined over the frequency range [2,3] GHz on a substrate with height h = 0.5 mm, relative permittivity r = 2.2 and loss tangent tanδ = 0.003.…”

In modern electronics, there are many inevitable uncertainties and variations of design parameters that have a profound effect on the performance of a device. These are, among others, induced by manufacturing tolerances, assembling inaccuracies, material diversities, machining errors, etc. This prompts wide interests in enhanced optimization algorithms that take the effect of these uncertainty sources into account and that are able to find robust designs, i.e., designs that are insensitive to the uncertainties early in the design cycle. In this work, a novel machine learning-based optimization framework that accounts for uncertainty of the design parameters is presented. This is achieved by using a modified version of the expected improvement criterion. Moreover, a data-efficient Bayesian Optimization framework is leveraged to limit the number of simulations required to find a robust design solution. Two suitable application examples validate that the robustness is significantly improved compared to standard design methods.

Based on the design and improvement of traditional hairpin microstrip bandpass filter, a cross-hairpin bandpass filter is designed in this paper. The filter is used in WCDMA operating between 1920GHz and 1980GHz. This paper analyzes the filters consisting of two hairpin resonators of differential coupling structures and their 3D models are simulated using Momentum based on ADS. Comparison of simulation and test results show that the improved filter has good passband and stopband characteristics.
