Abstract: The aim of this work is to design and implement a complex electronic device, known as an antenna switch, that allows to receive a high-frequency satellite signals in the UHF band via one of five connected antennas at a given time. This device is capable of automatic antenna switching according to non-geostationary satellite position, from which signal is received, thus with suitable antenna selection, is alternative to motorized directional antennas. The device consists of outdoor and indoor unit and Human-Machine interface (HMI). The outdoor unit is driven by a microcontroller which collect diagnostic data about proper function and controls the RF switch. The outdoor unit amplifies the UHF signal too. indoor unit with power inserter, diplexer and USB to serial converter, allows diagnostic data and commands transfer between outdoor unit and users computer with Human-Machine interface.
Keywords: Antenna switch; indoor unit; outdoor unit; RF circuit; RF switch; satellite; signal reception; UHF
