| Abstract: | The time domain electric field integral equation (TD-EFIE) in conjunction with the reciprocity principle is applied to synthesize the transmitting impulse signals on condition that the receiving signals have already been known. In addition, the effects of light-of-sight (LOS) and non-light-of sight (NLOS) propagation paths on the transmitting and receiving impulse signals are also discussed. In the analysis, impulse waveform and the shape of the antenna are arbitrarily given. The bowtie antennas and ultra-wide band (UWB) slot antennas are taken as examples and the computed results are compared with the known receiving impulse signals. The good agreement between them shows the correctness and effectiveness of the method proposed. |
