Modeling of Wire Antenna Arrays in the Frequency and Time Domain

The frequency domain and time domain analysis of straight-wire arrey is presented in the paper. The frequency domain modeling is based on the Pocklington integral equation set, while the time domain modeling is based on the Hallen integral equation set. Numarical solution of the Pocklington equations is provided by using the frequency finite element integral equation method (FD-FEIEM) and biconjugate gradient method (BiCGM), as well, while the Hallen integral equation set is solved via time domain version of the finite element integral equation method (TD-FEIM) and via the frequency domain method of moments (FD-MoM) combined with inverse Fourier transform. Some illustrative numerical results are enclosed in the paper.
