    Spline Horn Antennas

  • Custom design
  • Lightweight and compact
  • Designs for additive manufacturing
  • Perfect for satellites and smallsats
  • Anteral team has its longest heritage in the design of horn antennas since 1997. In particular, we design and fabricate spline horn antennas in a wide frequency range for many applications, such as satellite communications.

    This kind of antennas are completely custom, designed to fulfil the client specifications with outstanding performance. We have designs in the most important satellite frequency bands (Ka, Ku, X…). Apart from RF performance, they are also optimized for being as lightweight and compact as possible, features that are critical for space payloads.

    Moreover, we have experience in the design of spline horn antennas for additive manufacturing, considering the benefits and limitations of this kind of manufacturing technology.

    During these years, we have designed spline horn antennas for different satellite programs. Here there are some of them:
