Broad-Band Stub Design (Correspondence)

Mr. Muehe's results for broad-band stubs, while going beyond that of previous investigators, are similar to my design curves published earlier without detailed derivation. The main difference is that my curves were based on a formula involving the bandwidth as defined by the lowest and highest frequencies of zero reflection. Mr. Muehe's analysis is therefore superior to my simpler approach: my design curves erred on the safe side in predicting a slightly smaller bandwidth.
