Design Note DN0007 2.4 GHz Inverted F Antenna By Audun Andersen Keywords •CC2400 •CC2420 •CC2430 •CC2431 •CC2500 •CC2510 •CC2511 •CC2550 •CC2520 •CC2480 •PCB Antenna •2.4 GHz •Inverted F Antenna 1 Introduction This document describes a PCB antenna design that can be used with all 2.4 GHz transceivers and transmitters from Texas Instruments. Maximum gain is measured to be +3.3 dB and overall size requirements for this antenna are 11 x 4 mm. Thus, this is a compact, low cost and high performance antenna.

The easiest approach to implement the antenna in a PCB CAD tool is to import the antenna layout from either a gerber or 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 it is important to avoid placing components or having a ground plane close to the end points of the antenna. If the CAD tool being used doesn’t support import of gerber or DXF files, Figure 1 and Table 1 can be used. Figure 1.

IFA Dimensions Since there is no ground plane beneath the antenna, PCB thickness will have little effect on the performance. The results presented in this design note are based on an antenna implemented on a PCB with 1 mm thickness. SWRU120B Page 3 of 14 Design Note DN0007 4 Results All results presented in this chapter are based on measurements performed with CC2430DB [1]. 4.1 Radiation Pattern Figure 2 shows how to relate all the radiation patterns to the orientation of the antenna. The radiation patterns were measured with CC2430 programmed to 0 dBm output power. XY plane XZ plane YZ plane Figure 2.

YZ Plane Horizontal Polarization SWRU120B Page 10 of 14 Design Note DN0007 4.2 Reflection Figure 9. Measured Reflection at the Feed Point of the Antenna Figure 9 show that the IFA ensures less than 10 % reflection of the available power for a bandwidth of more than 300 MHz. A large bandwidth makes the antenna less sensitive to detuning due to plastic encapsulation or other objects in the vicinity of the antenna. 4.3 Bandwidth Another way of measuring the bandwidth after the antenna is implemented on a PCB and connected to a transmitter is to write test software that steps a carrier across the frequency band of interest. By using the “Max hold” function on a spectrum analyzer the variation in output power across frequency can easily be measured. Figure 10 shows how the output power varies on the IFA when the PCB is horizontally oriented and the receiving antenna has horizontal polarization. This measurement was not performed in an anechoic chamber thus the graph shows only the relative variation for the given frequency band.

FCC ID: 2BAUM-M04 RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093， Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f (GHz) ] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where f (GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Here, For BLE Transmit Frequency (GHz) Mode Measured Power (dBm) Tune-up power (dBm) Max tune-up Result 1g SAR power(dBm) calculation 2.402 GFSK -1.18 -1±1 0 0.3100 3 2.440 -1.38 -1±1 0 0.3124 3 2.480 -1.26 -1±1 0 0.3150 3 So a SAR test is not required.
