X Band Antenna

IQ Technologies for Earth and Space GmbH

■The Product
◎Overview

This COTS antenna is designed for pico and nano satellite applications to realize satellite links.
The mechanical dimensions fit a 1U CubeSat as well as larger satellites.
With circular polarization, the antenna provides a robust solution regarding the steering accuracy to the ground station antenna.
Due to the four combined patches, a high antenna gain can be achieved, considering small form factor requirements.
As RF interface, a robust SMA (female) connector is used. Four screws provide a proper mounting of the antenna.
The antenna backside shall be grounded properly to the satellite chassis. As dielectric,
ROGERS™ laminate for space applications is used. Patches and conductors are Cu with NiAu surface finish.
With the basic design TRL 9 has been achieved with various successful LEO missions.
Alternative designs for X band uplink frequency and X band downlink frequency are available.

■Features
▪ Flight grade tested design
▪ Patch antenna design
▪ Cost effective
▪ Short delivery time
