PCB Design Rules to Maximize Read Range

1 – Position of MAGICSTRAP® on PCB:

MAGICSTRAP® should be centered on the long side of the PCB to maximize read range.The following illustrates the relationship

between “X” length and read range using Type-3 board design.

2 – Eliminate conductive material under MAGICSTRAP®:

All layers beneath MAGICSTRAP® should be free of conductive material. This area should be equal or larger then the top layer

antenna design to maximize read range. The example below is using Type 3 design.
