IoT systems impose special requirements on wireless communication: end devices are often deployed in large numbers, frequently spread over wide areas, often mobile, energy-independent, and not always within the reach of terrestrial networks. A reliable, satellite-based connection is therefore of central importance.
Especially IoT applications in logistics, environmental monitoring, or agriculture demand antenna systems that are compact, energy-efficient, and cost-effective – and still reliably communicate with LEO or GEO satellites. The transmission of data over long distances requires targeted beam steering, as this is the only way to ensure a stable connection to the satellite even at low transmission power, without interference or data loss.
For energy-independent IoT devices that transmit only small amounts of data sporadically, conventional phased array antenna solutions are often too complex, too expensive, or too bulky. Particularly in large-scale networks with numerous connected devices, a well-thought-out antenna technology is needed that must also be economically scalable.
Our compact phased array antenna meets these requirements precisely. It offers high antenna gain and precise control while consuming minimal space and energy. It impresses with an intelligent design featuring a limited number of antenna elements, ensuring maximum performance. By using commercially available RF switches and delay lines instead of expensive, highly integrated beamformer chips, we reduce production costs and enable the production of smaller quantities – ideal for frequency bands where integrated solutions are not available.
