Abstract

Smart antennas with adaptive beamforming and -steering are required to enhance the overall system performance of future communication systems. Generation of multiple beams, side lobe attenuation and definite nulling are important features to reduce interference and to faciliate high-quality communication channels or to improve the accuracy of navigation data. This paper describes the design and fabrication of a compact C-band antenna with digital beamforming (DBF) as a breadboard model. It uses a 5x5 array of slot-coupled microstrip patches with RHCP that form a multilayer structure together with the networks for calibration and LO distribution. The complete antenna was teted with different parameter settings and the measurement results demonstrate its excellent versatile characteristics.
