ISISPACE S-band TMTC antenna is engineered for the commercial S-band uplink and downlink range (2025‑2110 MHz and 2200-2290 MHz). This lightweight, compact passive antenna is expertly designed for seamless integration with CubeSat platforms. Unlike competitors, it combines superior RF performance, structural compatibility, and proven flight heritage to ensure mission success. Its Rogers PCB design minimises signal losses compared to traditional FR-4 PCBs, delivering optimal efficiency for telemetry and payload data transmission.
