These COTS antennas are designed for small satellite applications to realize satellite communication links. Their mechanical dimensions fit CubeSats as well as larger satellites. Various designs of different frequencies are available, and customized solutions can be provided.

With circular polarization, the antennas provide a robust solution regarding the steering accuracy to the ground station antenna.

The design could be either as single patch antennas, dual patch antennas for separate Tx and Rx ports or quad patch antennas. With the dual patch antenna design the duplex filter requirements are minimized.

As RF interface a robust SMA (female) or an UMP connector is used. A minimum of four screws provide a proper mounting of the antennas. The antenna backside shall be grounded properly to the satellite chassis. ROGERS™ laminate for space applications is used as dielectric. The patches and conductors are copper with gold surface finish. The basic design has achieved TRL 9 with various successful LEO missions.
