Placement on Airbus A320 @ 1.5GHz

Airbus A320 model was imported from an IGES file. The airplane length is 37.6 m, wing span is 34.1 m. The model contains details such as windows and jet engine parts. No model repair was needed after import.
Using an adaptive algorithm, an all-quad mesh was created that represented all the details and yet created larger quads on the fuselage and wings to use the speed of higher order MoM to full extent.
With a few commands in WIPL-D Pro CAD, the model was split in half and simplified by removing all windows. A lambda/4 monopole was placed on the fuselage, gain of the system was computed at 833 MHz, with the airplane being 104 λ long at this frequency. read more

Automotive Applications

This article demonstrates application of WIPL-D Pro to the simulation of electrically large automotive structures. WIPL-D Pro is ideal for such applications because:
- The geometry can be easily imported from different CAD formats, and edited using the powerful user interface,
- Due to higher order basis functions, large structures are simulated very quickly.
We have simulated placement of two antennas:
- Microstrip patch antenna at 2.5GHz,
- Monopole antenna at 900MHz (GSM antenna).

Parabolic Dish in Vicinity of a Crane

A parabolic dish antenna is located in the vicinity of a tower crane. The task is to examine the influence of the crane to the radiation pattern of the antenna. The parabolic reflector diameter is 3.57 m and it is fed by a dual-mode horn with a choke. The system is designed for the operating frequency of 2.8 GHz. The crane is 30 m tall and its arms are 28 m long in total. Both the antenna and the crane are positioned above a perfect ground plane. The main radiation direction of the dish is towards the vertical boom, close to the place where the boom and the arms meet... read more

Simulation of a Frigate Warship Model on a PC

Frigate warship model is 117 meters long, and 12.6 meters wide. The ship is placed above a PEC plane that models the influence of the sea. A monopole antenna is placed on top of the comm tower. The simulation frequency is 240 MHz, which makes the frigate about 94 wavelengths long.
This model requires 78300 unknowns (equivalent to 49 GB of RAM). This requirement is not easily met by any workstation on the market. However, so much RAM is not needed for this simulation. The out-of-core solver makes any PC a powerful simulation environment. ... read more
