About
The PAN-185185-4-S is a passive flat panel array antenna operating in the S-band from 1.95 to 2.25 GHz, delivering more than 10 dBi of gain with circular polarization (LHCP or RHCP selectable). Its compact 3-layer PCB construction and flat profile make it suitable for integration on small satellites, UAVs, and compact satellite ground terminals where S-band TT&C, telemetry, or communications links are required.
The S-band frequency range covers multiple satellite services including deep space tracking, Earth observation satellite TT&C, mobile satellite communications (MSS), and UAV command and control links. The circular polarization design provides polarization insensitivity to satellite attitude variations, critical for CubeSat and small satellite TT&C links where attitude control may be limited.
The PAN-185185-4-S is designed as part of the Arralis/ReliaSat flat panel antenna product family and can be integrated with compatible S-band RF electronics for complete S-band satellite terminal solutions. Its combination of gain, compact form, and circular polarization makes it applicable to both ground-based terminals and spacecraft-mounted TT&C antennas for small satellite missions.
