A novel coplanar slow-wave structure that has the form of interdigitat
ed-meander line is proposed in this letter for use in MMIC's. A simple
analysis of this structure has been carried out by using empirical eq
uations available in the literature and with the aid of CAD packages.
A propagation velocity of about 2.8.10(7) m/s was measured. Comparison
s between theoretical and experimental results show good agreements.
