Hello,

We have several antenna options that are detailed in our application note AN058 linked here. We typically recommend the inverted F antenna that is described in this app note but this may be too large for your compact design. In addition to the antennas detailed in the AN058 app note, we've also identified the following two offerings from Kyocera AVX as potential options Option 1 and Option 2. Just please keep in mind that the Kyocera AVX antennas have not been fully evaluated by TI and you would need to contact them with any design and layout/implementation questions you may have.

Thanks,

Andrew

Hello,

The recommended RF front end is shown below. Keep in mind that the antenna matching (components Z60, Z61, and Z62) will need to be measured and adjusted for your design as differences in layout and stackup can greatly affect the required match for maximum power transfer.
