摘要

提出了一种结构简单的缝隙基板集成波导漏波天线，用于毫米波安全应用。该天线嵌入在双面覆铜基板中，制造成本低。该天线属于周期性漏波天线(PLWA)。天线的设计使-一阶空间谐波辐射到后象限。这导致在有限带宽下实现宽扫描角。介绍了100串联辐射槽天线的设计。在77 GHz ~ 81 GHz带宽范围内，所设计天线的模拟波束扫描角为20.4度。

Substrate Integrated Waveguide Leaky-Wave Antenna with Longitudinal Slots for Millimeter-Wave Security Applications

A slotted substrate integrated waveguide (SIW) leaky-wave antenna (LWA) with a simple structure for millimeterwave security applications is proposed. The antenna is embedded in a double-sided copper clad substrate and is manufactured at low cost. The antenna is categorized as a periodic leaky-wave antenna (PLWA). The antenna is designed so that –1st order space harmonic radiates into the backward quadrant. This leads to the achievement of a wide scan angle in a limited bandwidth. The design of the antenna with 100 series radiating slots is demonstrated. The simulated beam scan angle of the designed antenna is 20.4 degrees over the bandwidth from 77 GHz to 81 GHz.
