Hello,

We are using PNEV7462C  development kit.

which has 65x65 antenna we are looking for the antenna size to 15x25mm(ANFCA-2515-A02).

Can any one suggest the matching circuit for the above mentioned antenna and we have tried refernece matching circuit values mentioned in the datasheet as attached below and also see the current antenna component placement as attached below.antenna design and placement.png

The antenna tuning needs calculation with measurement on your custom antenna, you can not directly apply the matching circuits from the ref design to your custom board. Please refer to the following link for details.

Hello Kan_Li,

As we have missed the 30x50 Antenna board which came along with the development board (PNEV7462C) we would like to know the matching circuit values.

Thanks,

Sanath
