摘要
引入的ETS-GTEM5411电池的原始电阻网络尺寸为5.4 m×2.7 m×2.2 m (L×W×H)，低频吸收性能较差。本文提出了一种扇形电阻网络。在不考虑金字塔吸收器的情况下，在小于0.1 GHz的频率范围内，与原电阻网络相比，所提出的电阻网络使GTEM蜂窝的吸收性能提高了约10 dB。回波损耗在-20 dB以下的上限频率达到0.08 GHz。仿真结果表明，所提出的电阻网络对于不同尺寸的GTEM电池都是有效的。
The original resistive network of the introduced ETS-GTEM5411 cell with the size of 5.4 m×2.7 m×2.2 m (L×W×H) presents an inferior absorption performance at low frequencies. In this paper, a fan-shaped resistive network is proposed. Compared with the original resistive network, the proposed resistive network brings an improvement of about 10 dB to the absorption performance of the GTEM cell, over a frequency range less than 0.1 GHz, without considering the pyramid absorbers. And the upper limit frequency of the return loss below -20 dB reaches to 0.08 GHz. The simulated results show that the proposed resistive network is effective for GTEM cells of different sizes.
