The AntS from ISISPACE is a Satellite Antenna System with a frequency range greater than 10 MHz and a maximum RF power of 2 W. This antenna system uses linear or circular polarized antennas and has a return loss of greater than 10 dB at resonance frequency. It is controlled by dual redundant microcontrollers and can be interfaced to the satellite bus using the I2C protocol. The antenna system requires a supply voltage of 3-3.6 V and has a nominal power consumption of less than 40 mW. It has a mass of 89 g and measures 98 x 98 x 7 mm (stowed envelope). The AntS is suitable for applications such as CubeSat TT&C and CubeSat RF payloads.
