This communication introduces a CUDA-enabled GPU accelerated technique for broadband analysis of arbitrary 3D conducting body-wire radiating/scattering structure. The solution is based on the integral equation discretized by the method of moments (MoM) with the use of RWG-type basis functions. Wide-band data are generated from MoM simulation employing an adaptive frequency sampling of the observed quantity, and supported by implicit rational macromodelling via Stoer-Bulirsch algorithm. Numerical results are given for a helical antenna with a cylindrical cup reflector. The GPU-CUDA offers a speedup ratio nearly 9x over the CPU implementation.
