Abstract
In this paper, I designed and implemented 4*4 Beamformer using Butler Matrix for IMT-2000 band. I explained structure and function of Butler Matrix and analyzed phases and even-odd mode. Using this theory, it is designed wide band 90˚. Hybrid Coupler and simulated using Ensembele Tool. It is fabricated 4*4 Beamformer using Taconic TLC-32 dielectric substrate, and compared experimental results.
