Abstract

Straight microstrip lines alternately loaded with ground slots and open-end stubs are analyzed. Fabricated samples containing slots and stubs with various length combinations demonstrate constant slow-wave factors of 1.7 to 3.0 with negligible amounts of radiation loss and larger characteristic impedance tuning range. A slow-wave bandrejection filter at 1.8 GHz is built for performance comparison with a regular microstrip-line filter. Copyright
