IQ Spacecom X-Band Antenna
X-Band Patch antennas are provided for receiving and transmitting radio equipment for Cubesats as well as for bigger satellites. The antennas will be designed on customer-specific requirements in terms of frequency, bandwidth, size, connectors, gain, and pattern.
- Circular polarization (RHCP)
- High gain
- Ultra-small shape
- Low mass
- Compatible to 1U CubeSat
- Robust design
Lead Time: 3-4 months after confirmation of specifications
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 an 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.
