Using the concept of obtainable efficiency bandwidth to study tunable matching circuits

When designing tunable matching circuits for antennas, it is often difficult and cumbersome to study which matching circuit topology would be best for a given application. To speed up this design task we propose the concept of obtainable efficiency bandwidth related to a given matching circuit topology. The obtainable efficiency bandwidth is calculated at a given efficiency level for all the frequencies of interest as the bandwidth through an optimized matching circuit of the given topology. The obtainable efficiency bandwidth can be used to compare different matching circuit topologies and also taking into account the losses in the matching components.
