About
The ISISPACE S-Band TMTC Antenna is engineered for the commercial S-band uplink (2025–2110 MHz) and downlink (2200–2290 MHz) range, making it a true dual-band TMTC antenna. This lightweight, compact passive antenna is expertly designed for seamless integration with CubeSat platforms.
The antenna combines superior RF performance with structural compatibility and proven flight heritage to ensure mission success. Its Rogers PCB design minimizes signal losses compared to traditional FR-4 PCBs. The antenna provides a gain of >6 dBic in boresight and features RHCP polarization for optimal link margin.
With a diameter of 78 mm and total height of 16 mm (including connector), it fits within tight CubeSat volume constraints. Power handling up to 2 W ensures compatibility with standard CubeSat transmitters. Flight heritage since 2013.
