Hi All, i am designing NFC reader using PN65K. I am planning to complete the NFC module as a two layered board with the size of 67mmX25mmX5mm. Due to space constraints, I have to lay down the antenna in the Top and place all the components including the NFC controller, crystal and impedance matching circuit in the bottom layer. The attached document would depict the placement of the module. RED color indicates top layer, where as black color indicates bottom layer. I am concerned if 1. The components placed below the Antenna will be affected by RF radiations of the antenna 2. How could I minimize the effect of radiations on the components I place in the bottom layer. 3. will any Ground patch (below the NFC controller) in the bottom layer would affect Antenna performance.
