“…Recently, analytic TD solutions valid for arbitrary observation points off the reflector surface had been developed in [18] for a Huygen's source illuminations using TD-AI. In [5], a closed form solution of boresite radiation was developed for a defocused parabolic reflector antenna while [4] computed the radiation from a substitution of the parabolic reflector by an exciting V-antenna imaged from the reflector. The analytic transient solution of scattering from a reflector illuminated by a plane wave and Gaussian beams were developed in [16], [17] using TD-PO technique.…”

A time-domain (TD) analysis of ellipsoidal reflector antennas is presented to predict the transient scattered fields when it is illuminated by a cosine-tapered and transient-step feed radiation whose phase center is located at the nearby focus. A transient-step function of the feed's radiation is considered because it will produce an impulsive response near the second focus of the reflector as interested in the applications of impulse-radiating antennas. This TD solution is in a closed form and remains valid both near and far from the reflector, and can be used via the convolution theorem to efficiently obtain the early time transient fields generated by the same ellipsoidal reflector antenna when it is illuminated by a realistic finite-energy pulse which emanates as a spherical wave from the focus. Numerical results are presented for the transient fields both near and far from the reflector.Index Terms-Aperture integration, ellipsoidal reflector antennas, near-field focus and impulse-radiating antenna, time domain, transient analysis.

“…In doing this, it is desirable that in developing criteria for this selection the geometric dimensions of the antenna and the parameters of the drive pulse be taken into account. This problem has been solved for the aperture antenna [9]. It has been shown that the zone edges depend on the diameter of the aperture and on the risetime of the drive pulse.…”

Impulse radiating antennas (IRAs) are designed for radiating high voltage electromagnetic pulses. A four-arm parabolic reflector IRA is one of the most widly used IRAs for its strong boresight radiation field and high directivity. This paper investigates IRA models using software simulation developed based on the Method of Moment (MoM). The models are validated through comparisons with available theoretical and measurement results. Based on the IRA models, three types of radiation arm structures, wire, coplanar plate and bi-conical, are studied. This is to exam the impact of the radiation arm structures on the reflector IRAs. The results indicate that the coplanar plate arm IRA provides better antenna gain and radiation field performance in the frequency and time domain than the wire arm IRA, and the bi-conical arm IRA, similarly, performs better than the coplanar plate arm IRA.
