150GHz-Band Compact Phased-Array AiP Module for XR Applications toward 6G

In order to realize the practical application of sub-THz band wireless communication toward 6G, it is necessary to develop AiP modules with compact size and low-cost. This paper discusses the design of a miniaturized AiP module for high-speed wireless communication targeting XR applications in medical operating rooms as an example of 6G use cases. By integrating waveguide antenna array along with compact divider/combiner within the multilayer substrates, the module achieves a small form factor of 8.42 mm × 20.0 mm × 1.37 mm while integrating RFIC and peripheral surface mount components. The measurement shows a data rate of 40 Gbps at a communication distance of 3 m in the 150 GHz band, with an excellent transmission energy efficiency of 35.7 pJ/bit.
