Beamforming Network for 5G Applications

This paper is devoted to the design, analysis, and implementation of switched beamforming network operating at 5.2 GHz for 5G applications. It is intended to launch four beams. The Butler matrix feeding network is presented to electronically switch the beam in the desired direction. This work achieves a good approach to alleviate the problem of cross-over implementation and fabrication. A Four-element array of printed antennas is designed and fabricated. The network and array are implemented on Rogers RT/duroid 5880 substrate with a relative permittivity of 2.2 and a thickness of 1.04 mm. The different scattering parameters are simulated using both ADS and CST which conduct good agreement between the simulated and measured results.
