Small(er) Meander Antenna Dimensions

[Nate]

I have successfully implemented the meander PCB antenna outlined in this app note, however, I am looking for and cannot find information on a shrunken version of this antenna style that I know exists on a BLE module. The larger antenna has a copper footprint (not including keepout) of roughly 15mm x 5.5mm whereas the smaller antenna is roughly 9mm x 5mm, measured with calipers. Does anyone have knowledge of an app note or reference design with this smaller antenna?

Thanks in advance,

Nate

Hello Nate,

 

We do unfortunately not have any designs using a meander inverted-F antenna. But the nRF52840 dongle uses a regular meander antenna, with a approximate footprint of 10mm x 5mm(excluding the keepout).

The design files for the nRF52840 dongle are available for download, here.
