"The employment of WIPL-D is recommended due to its applicability to a variety of antenna shapes, its accuracy, and its speed of calculation and for the insight that it can provide to the operation of any antenna."
"It is a very versatile tool that can be applied to just about any antenna shape and configuration with good accuracy. WIPL-D is regarded as being a very powerful and useful tool for the antenna designer."
"The accuracy of WIPL-D generally seems to be at a very high level.
In summing up, all versions of WIPL-D have proved to be a fast, a very informative and an accurate tool for analyzing antennas."

"WIPL provided the means for designing a 21-element collinear array almost completely by computer simulation. One cycle of physical modeling of the array element was required to achieve the desired impedance matching. The new Windows version, WIPL-D, greatly enhances the software’s capability."

"I had the opportunity to test some programs for the EM simulation. Maybe WIPL-D is not as well known as other EM simulation programs promoted by RF media but I have to say WIPL-D is definitely the top leader in EM simulations.
My congratulation, great job +++."

"We use WIPL-D daily and have "invented" at least 300 new antenna designs with it."
"The GUI is functional and accessible to PC users. Affordable PCs with moderate speed and memory requirements can be used. Professional users find these codes to be quite user-friendly. Lastly, WIPL-D allows commercial companies to generate quickly new designs having optimum specifications, economical construction features and highly predictable performance without the need for time-consuming prototype fabrication, testing and tuning.
Seavey Engineering Associates (SEA) has used these codes for more than 5 years and has a WIPL-D design library of several hundred products. The company now routinely uses WIPL-D for many of its analysis and design activities."

"WIPL-D is currently being used at the University of Hawaii for new antenna designs as well as EMC applications. We have successfully modeled phase shifters and phased array antennas based on the ferroelectric materials technology. The ability to parameterize individual metallic plates gives us the insight required for accurate modeling, especially the high insertion losses associated with ferroelectric devices."

"WIPL-D (Wire/Plate) is a relatively new program that has the ability to model wires (similar to NEC4), plates, and dielectric volumes simultaneously. WIPL-D performed extremely well when compared to measurements on thick-wire multi-element Yagi antennas."

"WIPL-D is being used at the Instituto de Telecomunicações for analysis, design and optimization of antennas for microwave and millimeter wave applications, artificial dielectrics, and radiowave propagation related problems. The open format of input and output files of WIPL-D, together with its standalone kernel, enable easy manipulation of computed data even allowing for integration of WIPL-D into user developed codes."

"The customer support and technical expertise shown by the staff of WIPL-D is superb. Their staff provides quick turn-around and their products support both small and large projects. We've used other 3D EM packages (costing 10's of $K) and typically got referred to a sales representative when we had a problem, rather than to a cognizant engineer. WIPL-D is a high performance, moderately priced, mature product that any company looking for high quality EM design software should definitely consider."
