Abstract

In this paper, a 79 GHz microstrip antenna subarray, optimized for operation in a Phase Modulated Continuous Wave (PMCW) MIMO radar demonstrator is presented. The antenna combines all necessary features for this very specific type of applications. First of all, the spillover between transmit and receive channels in such a system is reduced by the combined effect of a microvia cage and the arraying of two elements. Second, it shows a wide band of 13.5%. Third, a wide beam in the E-plane (136 degrees), necessary for scanning, and a much smaller beamwidth in H-plane (36 degrees), advantageous to reduce mutual coupling, are realized. Finally, it has been fabricated with the advanced so-called “Any-Layer” technology. This technology is as accurate as other advanced technologies in the millimeter wave bands, but at a much lower cost, and thus very suited for mass production. The gain and radiation efficiency were simulated to be 7.44 dBi and 83%, respectively.

用于79 GHZ雷达应用的毫米波腔背微带天线阵列

本文提出了一种79 GHz微带天线子阵，该子阵经优化后可用于相位调制连续波(PMCW) MIMO雷达演示器。该天线结合了这种非常特殊类型应用的所有必要功能。首先，在这种系统中，通过微通孔笼和两个元件的排列的联合作用，减少了发射和接收通道之间的溢出。其次，它显示了13.5%的宽波段。第三，实现了扫描所需的e面宽波束(136度)和有利于减少相互耦合的h面小波束(36度)。最后，采用先进的“任意层”技术制作。这项技术与其他毫米波波段的先进技术一样精确，但成本要低得多，因此非常适合大规模生产。仿真结果表明，增益和辐射效率分别为7.44 dBi和83%。
