摘要

提出了一种基于半模波纹集成波导的电子扫描漏波天线。电子扫描是用变容二极管实现的。在5.8 GHz下，连续扫描角度在−24°~ +38°范围内，各扫描角度的增益均大于6db。同时，通过两个对称弯曲槽实现圆极化，轴比小于6 dB。由于半模波纹集成波导的优点，这种天线结构紧凑，有利于应用于一些无通孔的器件中。

An electronic scanning leaky-wave antenna based on the half-mode corrugated integrated waveguide

An electronic scanning leaky-wave antenna based on the half-mode corrugated integrated waveguide is proposed in this paper. Electronic scanning is achieved by the employment of varactor diodes. The scanning angle ranges from −24°to +38°continuously at 5.8 GHz, and the gain is greater than 6 dB at all scanning angles. Meanwhile, the circular polarization is achieved by two symmetrical bent slots and the axial ratio is lower than 6 dB. Because of the advantage of half-mode corrugated integrated waveguide, this kind of antenna is compact and beneficial to be applied in some devices without via hole.
