Antenna Requirements and recommendations for DECT NR+ antenna

[Alexander Eide Thorstensen]

We are developing HW that includes nRF9151 running DECT NR+ with the Wirepas stack for mesh connectivity between multiple units. The product is expected to move between geographies and the product must pass both CE and FCC certification. The radio will only be used for DECT NR+. 

This blog post indicates we will need an antenna that supports 1.88 to 1.93 GHz for DECT NR+ in most parts of the world:

The antenna solution on the nRF9151 DK seems overkill for DECT NR+ only applications. Will this antenna solution be a good fit for DECT NR+ with nRF9151 or can you make a recommendation?

Hello,

DECT NR+ only uses one frequency range. So, you don't need a multiband antenna like on the DK:

This is the antenna requirements Antenna requirements for nRF91 series. You need to contact an antenna manufacturer for getting assistance to find a suitable antenna for your use case in accordance with our requirements as well.
