Abstract :
WIPL-D was used to model and simulate an impulse radiating antenna (IRA) with a 46cm diameter paraboloidal reflector and 45 degree feed arms. Model views are shown and the results of frequency domain simulation up to 20GHz are shown to agree with results from published measurements. Beam patterns at three frequencies show the highly directional behavior of this antenna. The simulated frequency domain data is inverse Fourier transformed to obtain the time domain response to a Gaussian pulse input. This response is integrated to obtain the response to a step input, which compares well with the theorized step input response of the IRA.
