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.

“…While the current wireless local area network (WLAN) standard IEEE 802.11n has a maximum data rate of 600 Mb/s using a 40-MHz wide channel around 2.4/5 GHz, the IEEE 802.11ad standard provides up to 6.7 Gb/s per a 1.9-GHz wide channel around 60 GHz [1]. Advanced printed circuit board (PCB) materials such as low-temperature co-fired ceramic (LTCC) and liquid crystal polymer (LCP) have been used for 60-GHz packages to minimize feed loss [2,3]. These materials are costly, but their insertion loss is merely 1-2 dB lower than that of conventional FR-4 substrates depending on the feed length.…”
