Yb. Gan et al., ANALYSIS OF MICROSTRIP MULTIPORT JUNCTIONS USING THE MULTIMODE BOUNDARY INTEGRAL METHOD, Microwave and optical technology letters, 7(1), 1994, pp. 22-26
The Boundary integral method (BIM) is applied to a number of planar mi
crostrip multiport junctions. The E fields for coupling ports are expr
essed as multimode series, enabling direct calculation of S parameters
from the resulting matrix equation. Results obtained for cross juncti
ons, T junctions, Y junctions, and 90 degrees bends agree very well wi
th those obtained from full-wave analysis and other methods. (C) 1994
