To identify the ideal antenna for your application we have developed the Antenna Selector Tool which is a configurable filter to narrow down the results to match your exact requirements.

Antennas are a fundamental component of any wireless RF solution. Both, the most complex and the simplest wireless RF applications rely on antennas for end to end communication. The quality and performance of the antenna is critical to the correct operation of any wireless system, and it pays to specify it wisely.

Selection is normally left to the last minute, but design integration is key to getting the best deployment performance.

Wide Customer Base

The uses for antennas are endless and growing rapidly with IoT device availability and diversity. Siretta customers come from a wide range of markets:

  • WiFi linked Drones
  • Solar Farm: ‘Panel Data Collection’
  • Smart Energy Meters
  • Water Meters
  • Sensor Monitoring and Data Collection
  • Kiosks for Self-Check-In, Information Provision or as Sales Terminals

Antenna Customer Image

A wide selection of antenna designs, and technology support is available from our current antenna product portfolio and is growing based on customer needs and technology developments.

Antenna mounting

We offer a vast array of antennas from embedded PCB designs through to high gain directional pole mounted Yagi types.  The starting point in selection will be based upon the mounting design, simple stick in place, directly attached, embedded, magnetic, bolt on or pole/wall mounted. After the initial choice simply pick the communication technology that suits your application (2G/3G/4G, WiFi/Zigbee/Bluetooth, ISM Band/NB IoT/LoRa/SigFox, GPS or of course, a combination of 2 or 3 types).

Technology changes and moving to 5G

Networks and technologies are changing at a fast pace so ensure your designs are implemented with the future in mind. 2G and in particular 3G technologies have a limited life with migration to LTE 4G and upcoming 5G already undergoing city tests. The 4G to 5G technologies will migrate over time within the mid-band frequency spectrums (1GHz – 2.6GHz and 3.5GHz to 6GHz) from 2020 to 2021. 3G however will cut off from the low band (sub 1GHz) by the end of 2020.

Directional or Omni

A directional antenna is purposely designed to achieve a high gain in a narrow strip of space and is the best solution when communication between two points remains constant. If standard cellular communication is required from a fixed point to the network provider, then our Snyper tool can pin point the best provider and fixed tower position. A directional antenna will then give the most reliable connection.

Conversely when a device is mobile, an omni-directional antenna will enable the strongest signals to pick up from the closest or best performing network tower antenna. In a lot of instances, a large directional antenna is far too cumbersome and a small omni design is sufficient to provide the required connection.
