About
Rapidtek’s S-Band Dual-Frequency Patch Antenna covers two sub-bands simultaneously: Rx at 1980–2110 MHz and Tx at 2160–2290 MHz, enabling simultaneous telecommand reception and telemetry transmission on a single antenna element. This makes it particularly suited for NB-IoT and mobile satellite service (MSS) frequency allocations. The antenna achieves 6.2±0.4 dBiC peak gain on the Rx band with 93°±4° HPBW, and maintains an axial ratio below 3.5 dB across both bands. At 49 g it remains lightweight for CubeSat integration.
