Application Report 2.4-GHz Inverted F Antenna ABSTRACT This document describes a printed-circuit board (PCB) antenna design that can be used with all 2.4-GHz transceivers and transmitters from Texas Instruments ™ . The maximum gain when used on the reference board is measured to be +3.3 dBi, and the overall size requirements for this antenna are 25.7 × 7.5 mm (not including ground plane).

The easiest approach to implement the antenna in a PCB CAD tool is to import the antenna layout from a gerber file or a DXF file. Such files are included in CC2430DB reference design [1]. The gerber file is called Inverted_F_Antenna.spl and the DXF file is called Inverted_F_Antenna.dxf. If the antenna is implemented on a PCB that is wider than the antenna, avoid placing components or having a ground plane close to the end points of the antenna. If the CAD tool being used does not support importing gerber or DXF files, see Figure 1-1 and Table 1-1. The antenna impedance is tuned to 50 ohm on the reference board. The impedance will however be affected by different size and shape of the ground plane, objects in the antenna nearfield such as mechanical assemblies (housing, batteries, etc.), PCB thickness, PCB material and so on. It is therefore recommended to add a pi-network close to the antenna feedpoint for impedance matching. The results presented in this document are based on an antenna implemented on a PCB with a 1-mm thickness using standard FR-4 material. Figure 1-1. IFA Dimensions Table 1-1.
