Title: A Novel Approach to Synthesize Microwave Filters using Artificial Neural Networks
Abstract: AbstractEmergence of Artificial Neural Network (ANN) has provided newer avenues in the modeling and design of RF components. This paper proposes a novel synthesis procedure for the design and modeling of microwave filters using ANN. Building a feed forward neural network that corresponds to a Cauer ladder network of a planar filter is the key point of the paper. For validation purposes, the proposed approach has been used to synthesize a microstrip lowpass filter with a cutoff frequency of 1.5 GHz. This example filter design provides an insertion loss of around 2 dB in the pass band and a return loss of around 20 dB at the desired cutoff frequency. The design is verified by fabricating the filter on a glass epoxy substrate (ε = 4.6) with a thickness of 1.6 mm.Indexing terms: Back propagationMicrowave filtersModelingNeural networks Additional informationNotes on contributorsA ThenmozhiA Thenmozhi obtained her BE & ME degrees from Thiagarajar college of Engineering, Madurai Kamaraj University, India in 1988 & 2002 respectively.
