Abstract: This paper presents the design and performance evaluation of a multichannel adaptive beamforming antenna operating at 3.5 GHz. The proposed antenna is implemented using Rogers RT/Duroid 5880 and consists of a 28-element planar array capable of achieving a peak gain of 21.07 dBi. The system supports dynamic beam switching between one and five simultaneous beams, enabling flexible transitions among multiple beam configurations to enhance coverage and spectral efficiency. A MATLAB-based digital signal processing unit employing the MUSIC algorithm is used for accurate direction-of-arrival estimation and real-time control of complex array weights. The compact antenna structure (4.24λg × 5.99λg) ensures efficient beam steering with high directivity. The integration of HFSS electromagnetic simulations and MATLAB signal processing enables comprehensive analysis and optimization of the proposed system. The developed beamforming antenna is suitable for advanced wireless applications, including 5G/6G base stations, radar, satellite communication, and directional wireless sensing.
