WIPL-D white paper details full-wave simulation for predicting antenna coupling on electrically large platforms
↗
A WIPL-D-sponsored white paper describes a Method of Moments full-wave approach to predicting antenna coupling as low as -100 dB on platforms spanning hundreds of wavelengths, using higher-order basis functions and cavity-suppression techniques to reduce computational cost.
Engineers placing multiple radio systems on aircraft, ships, or vehicles need to know antenna isolation before hardware is built, and trial-and-error measurement is slow and costly. The white paper documents specific modeling techniques aimed at accurate low-level coupling predictions with fewer unknowns, though the content is sponsored and comes from a single source.

Higher-order basis functions allow patches up to 2λ in size, reducing unknowns compared to conventional low-order triangular meshing.
Three modeling techniques are compared on a metallic cube with two quarter-wavelength monopoles and a realistic airliner with five monopoles at 1.06 GHz, where the fuselage is approximately 140λ long.
Absorbing material and air-filled 'bubbles' suppress spurious cavity fields that corrupt low-level coupling results in closed metal platforms.
