摘要

本文提出了一种可提高增益并在宽边进行连续波束扫描的慢波基片集成波导周期性漏波天线.带有贴片的周期性盲孔组成的慢波结构可降低电磁波在基片集成波导中传播的相速度，导波波长可因此减少50%.与一般的基片集成波导周期漏波天线相比，这样的慢波基片集成波导周期漏波天线中相邻辐射单元之间的距离可减少一半，使得相同长度的慢波基片集成波导周期漏波天线中辐射单元的数量增加一倍.因此，慢波基片集成波导周期漏波天线的辐射效率和增益可以显著提高.此外，由于辐射单元下方慢波结构的贴片被延长，辐射单元的阻抗匹配被改善，反射波被抑制，在边射方向不存在开阻带.因此，辐射波束可以从后向到前向连续扫描.对所提出的天线进行了制作和测试，在13.4~15.4 GHz工作频率范围内，扫描角度达到72.7°，最大增益为8.47 dBi.测试结果与仿真结果十分吻合.

Abstract

A substrate integrated waveguide (SIW) periodic leaky-wave antenna (PLWA) with increased gain and continuous beam scanning through broadside is proposed by loading slow-wave (SW) structures. Slow wave structure in the form of periodic blind via-holes with loaded patches decelerates the phase velocity of the electromagnetic wave traveling in SIW

reducing the guided wavelength by 50%. Compared with normal SIW PLWA

the distance between the adjacent radiating slots in the proposed SW-SIW PLWA is decreased by half

allowing twice as many radiating slots in SW-SIW PLWA with the same length. Therefore

the radiation efficiency and the gain of SW-SIW PLWA can be significantly increased. Furthermore

the loaded patches of slow wave structure under the radiating slots are extended to improve the impedance match of the radiating slots and suppress the reflected wave

so the open-stopband (OSB)

which is a common drawback of the PLWA

is suppressed. In consequence

the radiation beam can scan from backward to forward direction continuously. A prototype of the proposed SW-SIW PLWA is manufactured and measured

the scanning angle of the proposed PLWA reaches 72.7° during the operating frequency range of 13.4~15.4 GHz with maximum gain of 8.47 dBi. The measured results agree well with the simulations.
