Chip Antenna Recommendations

[David Day]

Please provide recommendations (Supplier & Part Number) for chip antennas that have been used successfully in actual released FCC/ETSI certified Nordic-based product designs.

Hi,

Antennas are so application specific that I cannot point you to a specific antenna and say that this will work for your custom design. What you will have to do is to evaluate the size and space that you have available and see which antennas meet your specification.

In our reference designs we use normal 1/4 wave PCB antennas (in a "L" shape or meander), so we cannot give you a specific recommendation for chip antennas as we do not have that much experience with them.

If you have a look at chip antenna manufacturers site (Johanson, Murata, etc), you can sit down and look at the size specification and how they should be implemented, to see if they match your requirements. Any 2.4 GHz antenna would do.

Note that you will always require external components to tune your antenna (regardless of type) into 50 ohms. This is normally done by adding a PI-network: en.wikipedia.org/wiki/Antenna_tuner#Pi_network
