本文利用多导体传输线模理论，提出了一种新的E形贴片天线的电路模型。首先，在E形贴片天线上产生的电流模式，并从传输线模式理论推导出等效电路。对等效电路进行了详细的分析，得到了宽带特性。在驻波比准则下，推导出了理论最大带宽。最后，阻抗特性得到的电路进行了比较与全波电磁仿真。
This paper proposes a new circuit model for E-shaped patch antennas using the multi-conductor transmission line mode theory. First, the current modes generated on the E-shaped patch antenna are shown, and an equivalent circuit is derived from the transmission line mode theory. The equivalent circuit is analyzed in detail to obtain wideband characteristics. Then, the theoretical maximum bandwidth is derived under VSWR criterion. Finally, impedance characteristics obtained by the circuit are compared with full-wave electromagnetic simulations.
