Analysis of impulse-radiating antennas with centered and offset TEM feed structures

In this paper, two IRAs are numerically modeled. They are a center-fed IRA with a circular parabolic reflector and a conical coplanar feed and an offset IRA with an offset parabolic reflector and a conical feed with curved plates. The numerical model has been developed using the method of moments as implemented in the electromagnetic interactions generalized code.
