Circular Patch Array for Smart Antenna in C-Band

Smart Antennas have recently received increasing for improving the performance of wireless radio systems. The aim of the paper is twofold. One is to design and simulate an antenna array operating in C-band (4–8 GHz) and the other is the design of beamforming algorithm used in smart antenna. In this paper, the first module presents the design of eight circular sector patch elements suitable for beamforming technique in wireless applications. The second module suggests a MP (Matrix Pencil) to accurately estimate the DOA (Direction of Arrival) of the signal of interest, and LMS algorithm for beamforming technique to concentrate the power in the desired direction and nullify the power in the interferer direction. The modelling and simulation of antenna array is computed using HFSS. The beamforming algorithm is designed in Matlab.
