A new type of wave guiding structure is proposed is this paper. The guiding channel is developed on the full planar dielectric substrate and aligned with electromagnetic bandgap (EBG) units. Since the bandgap of these mushroom-like units is calculated with a coverage of the channel working band, these units are of great importance on ensuring the transmission efficiency and eliminating the coupling effect between channels. Then, this wave guiding structure is extended to the design of a six-element leaky wave antenna array with a complete size of 25.6 mm × 80.6 mm, which is working at Ku band from 12.0 GHz to 12.8 GHz and achieving a bandwidth of about 0.8 GHz, a gain of 11.36 dBi, and an efficiency of ca. 86.7% at 12.0 GHz. Within the working frequency band, this antenna topology achieves a frequency-dependent beam scanning in the forward directions, and it offers a potential for radar application on road speed detecting with low costs.

具有基于EBG的导波通道的全平面基板中的泄漏波阵列

提出了一种新型的波导结构。引导通道在整个平面介电基板上形成，并与电磁带隙（EBG）单元对齐。由于这些蘑菇状单元的带隙是在信道工作频带的覆盖范围内计算的，因此这些单元对于确保传输效率和消除信道之间的耦合效应非常重要。然后，这种波导结构被扩展到完整尺寸为25.6 mm×80.6 mm的六元素泄漏波天线阵列的设计，该阵列工作于12.0 GHz至12.8 GHz的Ku频段，并实现了约0.8的带宽。 GHz，增益为11.36 dBi，效率约为 在12.0 GHz时为86.7％。在工作频段内，
