Modeling of a Mobile Device Antenna
Application ID: 18837
Electrical components in wireless communication systems are designed to be small and lightweight while maintaining decent performance and efficiency. Antennas are essential components in mobile devices and are required to fit in the limited space allowed by industrial specifications.
To fulfill these requirements, a planar inverted-F antenna (PIFA) is a popular choice for miniaturized antennas in cellular phones. With simulation, the PIFA design can be tuned and extended to cover multiple frequency bands from cellular phones, Wi-Fi, and Bluetooth®.
The antenna in this introductory example is tuned only for the Advanced Wireless Services (AWS) band downlink frequency range. The impedance matching properties of the antenna are calculated in terms of S-parameters and the far-field radiation pattern is simulated.

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.
