Design of a miniaturized RF front-end module with antenna array for 5G millimeter-wave communication

The RF front-end module integrated with the antenna array is one of the key components in the system of 5G millimeter-wave communication, while helps to effectively reduces the insertion loss and circuit size. However, most of them are designed or assembled together which reduces the maintainability of the systems. This work presents a design of miniaturized RF front-end module integrated with antenna array as the core parts, which aims to provide the flexibility of maintenance for coming 5G millimeter-wave communication. The proposed design is introduced in detail, along with some simulated results. By comparing the integrated design and the independent design, it shows that the proposed design reduces the size of the circuit by 81% at the operating frequency.
