Indoor WPAN communication system using 2-dimensional array antenna in 60GHz frequency band

Abstract

2-dimensional antenna beamforming is studied in this paper. Beamforming technique can reduce interferences signals to increase SNR. Because of this advantage, beamforming technique was adapted for WPAN (wireless personal area network) using 60GHz band. Since this 60GHz band signal has a characteristic of low diffraction, it is good for indoor communication environment. In this paper, we analyze 60GHz frequency band characteristics such as reflection coefficient, path loss. Also, we propose a 3-dimensional tracking system with MUSIC algorithm. After simulation, one result shows that this system can track DOA (direction of arrival) using proposed method. Another result shows how many antenna numbers are suitable for indoor communication environment. As those two results, it can be adapted in 60GHz frequency band indoor communication.
