Implementation of a Smart Beam-Switching Antenna System

Abstract

Last decades have been marked by an increase in the number of users employing the various developed communication services. This has made it necessary to evolve the technologies used to better satisfy current demands. This paper shows the proposal for the development of a smart antenna array with beam switching for use in a communication system. It uses ARRadio-HSMC radio frequency cards as an implementation platform coupled to the TR4 development board. The proposed design allows dynamic control of the main direction of seven digitally synthesized radiation patterns, ensuring spatial coverage of an angular sector of 100º. Doing this project opens a line of work applicable in different systems, capable of easily adapting to complex antenna geometries and with the possibility of incorporating adaptive algorithms to increase the performance of the digital beamformer for each beam.
