An RFID System
Application ID: 1264
RFIDs are used in a multitude of applications such as tracking or identifying consumer products and their packaging.
An RFID system consists of two main parts:
- A tag or transponder with a printed circuit-board (PCB) antenna
- A reader unit with a larger RF antenna
This example illustrates the modeling of such a reader-transponder pair where the mutual inductance between the reader and transponder antennas are calculated.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
