Do I need to design a ground plane for the antenna?

The Astronode Patch Antenna generally works best with a ground plane of at least 65 mm x 65 mm. What’s more, Astrocast will be happy to assist you in selecting the best-suited antenna and its optimal implementation for your application. Get in touch to discuss your specific needs.

Do I need to design any RF circuitry between the Astronode S and the Antenna?

There is no need for additional components. However, the antenna line on the PCB has to be carefully designed to match 50 Ohm impedance.

Can I use the Astronode Patch Antenna for both the Astronode S and my GNSS receiver?

Yes, our multi-band antenna can serve both the data communication over the Astrocast network as well as receive GNSS data for a third-party receiver. Please refer to our technical documentation for design guidelines.
