Reducing EMC emission
To reduce the EMC emission and transmission of stray harmonic frequencies, the
antenna should have partial electrical shielding. This is easiest to implement using a
PCB antenna and a 4-layer board. The shielding loops are on the top and bottom layers
and cover the antenna track area. These shielding loops must not be closed. The
shielding must be connected to system ground at one point only. The coil is routed on
the first inner layer. The optional centre tap of the coil is connected to ground with a via
as shown. The connection of the coil ends to the matching circuit should be routed close
together to avoid additional inductance.
