Analysis of the Coverage of Lossy Tunable Matching Networks

Research output: Contribution to conferenceConference Paper


Tunable matching networks are essential for frequency-agile wireless systems. Practical components used in these networks have limited quality factors, thereby introduce losses. In this work, the effect of lossy components on the area a tunable matching network can cover is analyzed theoretically and verified by measurements. The proposed analysis method can be applied to any network with lumped components or transmission lines. As proof of concept, a T-type example
network has been investigated. The proposed method has been found to accurately predict the shrinkage in coverage due to losses as verified by measurements. The decrease in the coverage can be considerable, which indicates the significance of loss analysis in the design of tunable matching networks.
