2.8 RF performance and the use of magnetic sheet
• RF (communication) performance is closely related to the effectiveness of the magnetic and metal sheets
used below and around the antenna of the module.
• RF performance varies considerably, depending not only on the magnetic permeability (μ’, μ”),
dimensions and thickness of the magnetic sheet but also on the dimensions and material of the metal
sheet used. There is also a possibility that it is affected by metal in the installation environment.
sheet used. There is also a possibility that it is affected by metal in the installation environment.
• The module is designed to be used with the specified magnetic and metal sheets attached in advance to
control the magnetic field generated by the antenna, as well as to minimize the possible effects from the
installation environment.

This contributes a great deal to the reduction of the time required for weighing the effects of the installation
environment and evaluating the module’s RF performance.
