Switched Beam SIW Horn Arrays at 60 GHz for 360° Reconfigurable Chip-to-Chip Communications With Interference Considerations

Traditional wired interconnects in multicore multichip (MCMC) systems can be replaced with chip-integrated switched beam antenna arrays to provide reconfigurable chip-to-chip communications. By simply switching the directive beams of arrays, chips made dynamically communicate their surrounding neighbors. Radiation from unintended direction, however, causes interference when multiple pairs are simultaneously communicating. In this paper, noise and limitations such concurrent communication analyzed at 60 GHz for channels defined IEEE 802.11ay standard. Each array consists eight substrate integrated waveguide (SIW) horn elements printed on a thin dielectric substrate. The individually excited produce endfire beams, providing full 360° coverage, horizontal plane. acts as hybrid space-surface wave interconnect (HSSW-I) that allows near-field, space surface coupling occur between thus, increases interchip transmission. link parameters dictate signal-to-noise-plus-interference ratio (SNIR) established by considering all major components. maximum achievable data rates then determined based SNIR, calculated measured simulated transmission coefficients arrays.
