2.4-GHz Inverted F Antenna Design and Measurement Report

Antenna Spec

This application report from Texas Instruments provides a comprehensive guide to designing and implementing a 2.4-GHz Inverted F Antenna (IFA) on a printed circuit board (PCB). The document focuses on achieving optimal performance with TI's 2.4-GHz transceivers and transmitters. It details the antenna's dimensions, measurement results, and bandwidth characteristics.

The report emphasizes the importance of precise replication of the antenna dimensions, recommending the use of Gerber or DXF files included in the CC2430DB reference design. It also addresses impedance matching considerations, highlighting the impact of ground plane size, nearby objects, PCB thickness, and material. The document presents radiation patterns, reflection measurements, and bandwidth analysis, demonstrating the antenna's performance within the 2.4-GHz ISM band. The antenna achieves a maximum gain of +3.3 dBi and maintains stable performance across various operating frequencies and antenna positions.
