Data Downlink Antennas

forme 2
Anywaves X-Band antennas are designed for data downlink and payload telemetry in space missions.

Our antennas are essential for providing reliable and accurate communication between your satellite and ground stations.

The data downlink function involves transmitting large amounts of data from your satellite to the ground, including high-resolution images and other valuable information. Anywaves offers two different types of X-Band antennas. Our High-Gain X-Band Payload Telemetry Antenna is designed for reliable and high-performance data transmission from your payload. It provides a narrow-beam coverage, and features an excellent axial ratio.

Additionally, our High-Gain X-Band Dual-Circularly Polarized Antenna provides superior performance thanks to its dual-circular polarization feature, making it ideal for high data rate missions, such as earth observation programs, scientific missions, etc. We also offer a Test Cap for X-Band antennas, enabling you to perform end-to-end radio frequency testing directly on your spacecraft.



At the Technical Projects Department, we’re committed to developing and designing state-of-the-art X-Band antennas for Data Downlink applications that deliver outstanding performance and compactness. Our aim is to provide innovative antenna designs that meet the needs of space missions, while leveraging our flight-proven expertise in materials and quality. Our antennas undergo a thorough process, starting from concept creation and design, to testing, qualification, and marketing, always with a practical innovation perspective. Our ultimate objective is to create pioneering and top-performing X-Band antennas that pave the way for the future of space communication, ensuring reliable data transfer between the satellite and ground station.

Testing process

To ensure the durability and performance of our X-Band Data Downlink antennas in the harsh space environment, we subject them to a series of rigorous tests. Our qualification tests evaluate the ability of our antennas to withstand the various life cycles of a space product, while our acceptance tests are performed on each flight model to ensure that the delivered product meets the required functionality and durability criteria. By conducting meticulous and comprehensive testing on all of our antennas, we guarantee the reliability and long-term functionality of our products, giving our customers peace of mind and confidence in their space missions.



Our industrialization process for X-Band Data Downlink and Payload Telemetry space antennas is carefully crafted to ensure that we deliver high-quality products to our customers within the expected timelines. To achieve this, we have optimized our production processes to effectively manage large-scale production while maintaining strict quality control measures. Our philosophy of “less is more” allows us to create innovative and reliable space antennas that meet the needs of the modern space industry. We believe that our focus on quality and efficiency is essential to delivering the best possible products to our customers.

Flight Heritage

ANYWAVES has accumulated extensive experience and expertise in the field of X-Band antennas for data downlink applications. Our past successes in developing and launching X-Band antennas into space have given us valuable insights and knowledge that enable us to provide high-quality products to our customers. We take pride in our ability to rapidly progress from prototype designs to fully operational flight models, demonstrating our commitment to innovation and reliability.


Do you propose an EM (Engineering Model) and/or a FM (Flight Model) item?

As on all our products, we propose two different versions for our Data Downlink antennas: an engineering model and a flight model. Both have the same electrical performances as they use the same materials and processes. On flight models, we perform meticulous and rigorous acceptance tests.

What are test caps useful for? Can I use your test caps on any antenna?

A test cap is the perfect tool to simplify your antenna testing process. It allows highly reproducible measurements in all your environments such as clean rooms or thermal chambers. Using this equipment eliminates the need for RF tests to be carried out in an anechoic chamber, saving you significant amounts of time and money.


However, it’s important to note that our test caps are specifically designed for use with ANYWAVES antennas. Due to variations in antenna designs and specifications among different suppliers, we cannot guarantee compatibility with antennas produced by other suppliers. To ensure optimal protection and performance, we recommend using our test caps exclusively with ANYWAVES antennas, as they are tailored to fit our specific antenna models.

What if my specifications are different from the Data Downlinks antennas on your website?

At ANYWAVES, we understand that every project may have unique requirements. We offer customization options to tailor our antennas to your specific needs. Our experienced engineering team can work closely with you to develop custom antenna solutions that align with your specifications. Whether it’s modifying existing designs or creating entirely new antennas, we are committed to delivering antennas that meet your exact requirements. Feel free to contact us to discuss your specific needs, and we’ll be glad to assist you with a customized solution.

I don’t know which Data Downlink antenna to buy, can you help?

Absolutely! We understand that selecting the right Data Downlink (X-Band) antenna is crucial for efficient data transmission. Our team of experts is here to guide you in finding the perfect solution. By understanding your specific requirements, such as data transfer rates, bandwidth, beamwidth, and mechanical constraints, we can provide personalized recommendations from our range of Data Downlink antennas. We are committed to helping you choose the optimal antenna that ensures reliable and high-speed data downlink for your space applications. Feel free to reach out to us for expert guidance and support in selecting the right Data Downlink (X-Band) antenna.

Is the EIDP (Engineering Item Data Package) included? What does it contain?

Yes, the EIDP (Engineering Item Data Package) is included with our ANYWAVES antennas. The EIDP contains comprehensive documentation that provides essential technical details and specifications of the antenna. It typically includes :

  • Acceptance test reports
  • ICD (Interface Control Document)
  • Mechanical envelope
  • User Manual
  • Certificate of conformity


We ensure that the EIDP accompanies each antenna purchase to support your integration and operational needs.

Are your Data Downlink antennas in reception or in emission ?

Our Data Downlink antennas are primarily designed for emission purposes. They are optimized to send data signals to spaceborne systems, such as satellites or spacecraft. However, even if the antenna has been thought to work mainly on emission, it’s also perfectly capable to work on reception if needed.

What are the key features of a Data Downlink antenna?

Our Data Downlink (X-Band) antennas at Anywaves offer several key features that make them essential for efficient data transmission in space applications. These antennas are designed to operate within the X-Band frequency range, providing high data transfer rates and increased bandwidth capabilities. With their compact and low-profile volume, they possess high-gain characteristics ensuring reliable and accurate downlink communication with spacecraft. Our X-Band antennas are built to withstand harsh environmental conditions, maintaining optimal performance and durability throughout missions. With their exceptional data transfer capabilities and reliability, our X-Band antennas are the ideal choice for space data downlink requirements.

Can I buy a single antenna or is there a minimum order? How quick can I receive my order?

Whether your project is big or small, we can provide a single EM antenna for testing as well as cater for volume orders. Depending on your lead time and our availibility, we may even be able to ship it within a few days!
