Antenna Placement on Electrically Large Platforms

WIPL-D Pro is a frequency-domain MoM based code which enables very accurate EM simulation of arbitrary 3D structures. MoM demands far less memory and time resources for open region problems on PC computers or inexpensive workstations.

The WIPL-D suite offers highly efficient parallelization on all modern CPU/GPU platforms. Matrix fill-in is greatly speeded up on inexpensive multithread desktop PCs, while matrix inversion for electrically large problems relies to WIPL-D GPU solver.

The features intended for antenna placement problems is “smart reduction” or shadow region. The number of unknowns is reduced 3-10 times, with preserved accuracy (radiation pattern or coupling between multiple antennas).

λ/2 dipole is placed above a large payload fairing (8.66 m long). At 2 GHz, the fairing length is around 58 λ. With one symmetry plane applied, the model requires 44,614 unknowns. After reductions, the problem is solved with as few as 5,000 unknowns (9x reduction). Discrepancies occur at side-lobes with levels lower than 25 dB.
