Some investigations on the admittance characteristics of I-slot in a rectangular waveguide

Inclined slots in a narrow wall of a rectangular waveguide are analyzed by different researchers. However, it is difficult to accommodate a slot of resonant length in the narrow wall. In view of this an I-slot which can resonate without any practical constraints is investigated in the present paper. The results of investigations consist of data on slot admittance parameters, coupling and VSWR.
