Packaging Solution for a Millimeter-Wave System-on-Chip Radar
IEEE Transactions on Components, Packaging and Manufacturing Technology, vol. 8, no. 1, pp. 73 - 81, DOI: 10.1109/TCPMT.2017.2758725, 2018.
Abstract: In this paper, a packaging solution for millimeter-wave system-on-chip (SoC) radio transceivers is presented. The on-chip antennas are realized as primary radiators of an integrated lens antenna which offer high bandwidth and high efficiency. The package concept includes a high permittivity silicon lens which serves additionally as heat sink and a quad flat no-lead package which is mountable on a standard printed circuit board (PCB). The electrical and thermal properties of the package are investigated through simulations and calibrated measurements. The concept is verified by realizing a complete radar sensor. The manufactured SoC radar frontend is soldered on a standard PCB which includes the baseband circuitry for a frequency-modulated continuous wave radar and finally, measurements are performed to compare the superposed radiation patterns of the transmit and receive antennas with simulations.

Two-Level Spatial Multiplexing Using Hybrid Beamforming for Millimeter-Wave Backhaul
IEEE Transactions on Wireless Communications, ISSN: 1536-1276, DOI: https://doi.org/10.1109/TWC.2018.2832084, 2018.
Keywords: Line-of-sight MIMO, millimeter wave communications, wireless backhaul, hybrid beamforming, analog/digital beamforming, spatial multiplexing
Abstract: Spatial multiplexing is an important factor usable for improving the throughput of future millimeter-wave (mmwave) backhaul links. One conventional strategy in mm-wave multiple-input-multiple-output (MIMO) systems uses densely packed antennas and exploits the spatial signature of multiple paths. Meanwhile, spatial multiplexing over a single Line-of-Sight (LoS) path, known as LoS MIMO communication, offers an alternative option with widely spaced antennas exploiting the phases of spherical waves. In this work, we firstly show that those two conventional approaches exploit two different degrees in the channel matrices, which we denote as inter- and intrapath multiplexing, respectively. Then we show that the two kinds of spatial multiplexing can be jointly exploited and identify their different requirements on system design. Fulfilling all requirements simultaneously, we propose a system with multiple widely spaced subarrays. With the help of analog beamforming, the intra-path multiplexing of conventional LoS MIMO systems can be introduced to other non-LoS paths owing to its robustness. Merging the two kinds of spatial multiplexing in a combined channel model and connecting it with a hybrid beamforming architecture, the proposed system achieves spatial multiplexing of a higher order than conventional ones. Simulation results for a backhaul scenario illustrate that the channel of the proposed method has higher ranks than that of conventional approaches.
