Abstract :
The characteristics of centered-inclined, longitudinal/transverse, and compound slot couplers for slot array applications are studied. The variation of normalized resonant length as a function of slot offset and tilt is shown. Both mod S/sub 11/ mod at resonance and the phase of mod S/sub 31/ mod at resonance are shown as functions of offset and tilt.<>
