Research on the Receptive Station of a Miniature Wireless Video Communication System

摘要

In this paper the receptive station of a miniature wireless video communication system is presented. It consists of a high gain helix antenna, a low noise amplifier (LNA), an analog satellite receptor and a computer with a digital video card or a monitor. By using matlab6.0 and ADS2002 (microwave simulation software), we can get the optimum parameters of the high gain antenna and design LNA adapting to the system. The gain of the helix, antenna (44°directional angle) is about 13dB and that of the LNA is about 15dB. The system is successfully tested on the MAVs with 320mm wingspan.
