Step 7: Select View Plot to see the frequency response and VSWR bandwidth.

Notice from the marker data that the 1.05 VSWR bandwidth extends from 875 MHz to just beyond 1125 MHz yielding a 25% bandwidth centered around 1000 MHz. Since the lines are about half their original length, the 1.05 VSWR bandwidth is about half of the 500 MHz bandwidth obtained with the full length lines (used in DEMO 3).  Also, a 1.01:1 VSWR match (S21 » 0 dB) exists at the 1 GHz band center.
