The ISISPACE S-Band TMTC Antenna is a passive CubeSat telemetry and telecommand (TMTC) antenna covering 2025-2110 MHz for uplink and 2200-2290 MHz for downlink.[1] It is built on a Rogers printed circuit board (PCB) with IPC-A-610 Class 3 assembly. ISISPACE reports flight heritage in 2025 and compatibility with its own transceiver and with other manufacturers' systems.[1]
The published gain is greater than 6 dBic at boresight at centre frequency, with a maximum of up to 8 dBic. The half-power beam width is 100 degrees.[1] Return loss exceeds 10 dB, polarisation is right-hand circular (RHCP) and power handling is 2 W. The axial ratio is listed as below 3 dB for 80 degrees.[1]
Mass is below 60 g. The antenna is 78 mm in diameter and 16.0 mm high including its straight MMCX connector, and it operates from -20 to +60 C.[1]
Qualification testing covers functional, thermal-vacuum and thermal-cycling tests, and acceptance testing covers functional and thermal-cycling tests.[1]
