Modeling of a Mobile Device Antenna

Application ID: 18837

Electrical components in wireless communication systems are designed to be small and light for portability and productivity 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 this requirement, a planar inverted-F antenna (PIFA) is common and a popular choice for miniaturized antennas in cellular phones. 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:
