Abstract: Aiming at the inherent drawbacks of conventional cable and connector assemblies, such as bulky physical dimensions, cumbersome installation procedures, limited axial and radial misalignment tolerance, high risk of accidental disconnection, and restricted service life, this work proposes a non-contact interconnection scheme as an alternative solution. The proposed assembly consists of a pair of transceivers designed for paired operation, which can fully replace traditional mechanical connectors. It features enhanced floating tolerance and free non-contact disconnection capability, integrating both wireless power transfer and high-speed wireless data transmission functionalities.Three types of microwave and electromagnetic components are designed in this study. Specifically, a planar spiral coil operating at 100 kHz is developed for wireless power delivery, while a 2.5 GHz PIFA antenna and a 60 GHz high-gain antenna are designed for wireless data communication. On the basis of the established antenna simulation models, the mutual crosstalk between different antennas as well as the self-interference between identical antennas is systematically investigated. The research includes the analysis of electromagnetic interference between the power transfer coil and the 2.5 GHz/60 GHz data antennas, the mutual interference between the 2.5 GHz and 60 GHz antennas, as well as the co-channel interference between homogeneous 2.5 GHz antennas or 60 GHz antennas. The intensity of mutual crosstalk among the three types of components operating simultaneously is quantitatively evaluated, and corresponding results are analyzed in detail.Wireless power transfer is realized based on 100 kHz magnetically coupled resonant technology. Parameter optimization of the power transfer coil is performed via ANSYS Maxwell simulation. The transmission efficiency reaches 99.97% at a 1 cm gap and 98.91% at a 3 cm gap respectively. For data transmission, a multi-modal communication strategy is adopted. The designed 2.5 GHz V-shaped folded PIFA antenna achieves an impedance bandwidth of 290 MHz ranging from 2.38 GHz to 2.67 GHz, with a peak gain of 3.4 dBi. The 60 GHz open-ended waveguide antenna exhibits a bandwidth of 8 GHz and a gain of 7.65 dBi, which can satisfy the transmission requirements of various high-speed bus interfaces with different data rates.In addition, system-level electromagnetic crosstalk is analyzed using CST simulation. The results demonstrate that the isolation levels between the 2.5 GHz antenna and the 60 GHz antenna, as well as between the data antennas and the power transfer coil, are mostly below -60 dB, indicating extremely weak crosstalk and satisfactory electromagnetic compatibility within the integrated non-contact interconnection system.
