| Abstract: | On the basis of EFIE-MoM and wire-surface basis function,the EM characteristics of Koch fractal antenna mounted on complex metal objects are analyzed.Theoretical models and a computer program are verified by some examples of conventional monopole antennas on metal objects.The input impedance and radiation pattern of Koch fractal antenna mounted on complex metal objects are calculated.The obtained numerical results are analyzed and some conclusions are deduced. |
| Keywords: | Method of moments Wire-surface junction Koch fractal antenna |
