Abstract EN
A novel design of a compact 4×4 Butler matrix is presented.
All the design is based on the use of a Lange coupler with certain geometrical characteristics.
This matrix occupies only 20% of the size of the conventional Butler matrix at the same frequency (80% of compactness).
To examine the performance of the proposed matrix, the Lange coupler and the Butler matrix were simulated using Momentum (ADS) and IE3D softwares.
Simulation results of magnitude and phase show a good performance.
Furthermore, a four-antenna array was also designed at 2.45 GHz and then connected to the matrix to form a beamforming antenna system.
As a result, four orthogonal beams at −45∘, −15∘, 15∘, and 45∘ are produced.
This matrix is suitable for wireless application at ISM band of 2.45 GHz.
