本文首先介绍了新发明的倒置微带间隙波导（IMGW）的解析解。应用经典变分法得到了IMGW的特性阻抗、介质损耗和导体损耗。利用商用软件CST验证了该方法计算的IMGW特性阻抗和损耗。此外，我们还从理论上证明了IMGW中的电磁能量的总损失是远远低于覆盖微带线在毫米波（mmWs）。因此，IMGW在毫米波高增益、高效率阵列天线中具有比覆盖微带线更大的优势。
This paper initially introduces analytical solutions to newly invented inverted microstrip gap waveguide (IMGW). By applying the classical variational method the characteristic impedance, dielectric loss, and conductor loss of the IMGW are obtained. The calculated characteristic impedance and losses of IMGWs with the present analytical method have been verified by commercial software CST. Furthermore, we have theoretically proved that the total loss of electromagnetic energy in the IMGW is much lower than that of covered microstrip line in millimeter waves (mmWs). Thereby, the IMGW has big advantages over covered microstrip lines for high-gain, high-efficiency array antennas in mmWs.
