AbstractA 2-D Butler matrix feed network is designed, implemented, and integrated with a 60-GHz 2 × 2 circular patch planar array for chip-to-chip communications. The realized antenna module is a thin multilayer microstrip structure with a footprint small enough to fit over a typical multicore chip. The network enables end-fire (azimuthal) scan of the array main beam in the four diagonal directions, which is demonstrated for the first time here. The antenna module provides a seamless and practical way to achieve reconfigurable interchip communication in multicore multichip (MCMC) systems. A hybrid space-surface wave interconnect is proposed that takes advantage of surface wave coupling. The matrix is a four input, four output i.e., 4 × 4 network consisting of four interconnected quadrature (90°) hybrid couplers. A multi-antenna module (MAM) consisting of five antenna modules that emulates diagonal interchip communication in MCMC systems is fabricated. The simulation and measurement of transmission coefficients between the antenna modules on the MAM are performed and compared.
