Cassegrain Antennas with Diameters Up to 200 λ

Very large Cassegrain antennas are usually simulated using specialized asymptotic methods. However, WIPL‑D Pro simulates antennas of this type using very accurate and very fast Method-of-Moments with higher order basis functions which results in very high numerical efficiency. Due to…

The application note contains basic information about this type of reflector antennas. The WIPL-D MoM implementation is particularly well suited for simulation of reflectors, which is elaborated in details (quadrilateral elements of 2 lambda by 2 lambda, up to the…

Two models of circular horn antenna were simulated using the WIPL-D software. Special attention is devoted to the dielectrically loaded horn antenna. The influence of the dielectric loading is highlighted and it is the most noticeable in radiation back lobe…

The application note presents WIPL‑D Pro models and simulation results of one of the simplest and widely used antennas – rectangular horn antenna at 10 GHz. Half and quarter of the model were simulated in order to demonstrate the capabilities…

Multi-hole waveguide coupler is extension of single-hole coupler, designed to increase the operational bandwidth. The performance is based on size of the coupling holes and distance between them, since it is important to achieve wave amplification in the through-direction and cancellation in the opposite…

This application note presents S-parameters obtained with effective usage of WIPL-D Fitter, number of unknowns, computer memory required and simulation time per frequency obtained after simulation of two passive, microstrip, band pass filters. The first simulated filter is interdigital, while the second one is…
