M. Kahrizi et al., ANALYSIS OF A WIDE RADIATING SLOT IN THE GROUND PLANE OF A MICROSTRIPLINE, IEEE transactions on microwave theory and techniques, 41(1), 1993, pp. 29-37
An analysis of a wide rectangular radiating slot excited by a microstr
ip line is described. Coupled integral equations are formulated to fin
d the electric current distribution on the feed line and the electric
field in the aperture. The solution is based on the method of moments
and using the space domain Sommerfeld type Green's function. The infor
mation about the input impedance or reflection coefficient is extracte
d from the electric current distribution on the microstrip line utiliz
ing the matrix pencil technique. The theoretical analysis is described
and data are presented and compared with other theoretical and experi
mental results.
