When the minimum test separation distance is <5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. Measurement Result For BT: The max conducted power including tune-up tolerance is 0 dBm (1 mW). [(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)] =1/5*(√2.480) = 0.3< 3.0 For BLE: The max conducted power including tune-up tolerance is -3 dBm (0.5 mW). [(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)] =0.5/5*(√2.480) = 0.2< 3.0 Result: Compliant.

ThePCB antenna used on the reference design is described in this a pplication note. Even if the antenna presented is for a it can be use d in a ll designs, 2.4 GHz especially where smallre quired s pace is for the antenna. This application note describes the antenna dimensions, the RF performance Figure 1: Manufacture：Xiamen Renhe Sports Equipment Co.,Ltd Address：4/F, NO.1129 Jicheng Road, Industrial Concentration Zone,Tong'an District, Xiamen, Fujian, P.R. China BK3266L BK3266L ANTENNA REPORT BK3266L ANTENNA DESIGN ThePCBantennaonthe referencedesignisa meande「ed InvertedF Antenna(IFA) . TheIFAwasdesigned tomatchanimpedanceof 50ohmat2.45GHz.Thus no additional mat ching components are necessary. 2 Design Goals The reflection at the feed point of the antenna determines how much of the applied power is delivered to the antenna. A reflection of less than -10 dB across the 2.4 GHz ISM band, when connected to a 50 ohm source, was a design goal. Reflection of less than斗O dB, or VSWR less than 2, ensures that more than 90% of the available power is delivered to the antenna. Bandwidth is in this document defined as the f「equency band where mo「e than 90% of the available power is delivered to the antenna. Another design goal was to fit the size of the PCB antennaona connected to a computer. andtoobtaingoodpe时ormance alsowhenthedongleis 2.1 Simulation IE3D from Zeland, which is an electromagnetic simulation tool, was used to design the antenna. The accuracy of the simulation is controlled by the mesh. An increase of the mesh increases the simulation time. Thus, for initial simulations mesh = 1 should be used. When a fairly good result is achieved a higher mesh should be used to obtain more accurate results. Comparison of simulation and measurement results shows that the measured reflection is between the result obtained with mesh = 5 and mesh = 1 ; see Figure 2 for details. 2.2 -3 - 12 也 飞， - 21 -2 7 - 1 5 · 1 8 - 9 ...• Simulated mesh6 -Simulated mesh1 一 ···· ·＆T o －－， ．．．． ，，，， ．．．．．．．． 01· …－ Measured free s p ,oe 3 , ·24 · 。 -3 “ 6 - 9 - 1 2 国 飞， · 1 5 - 1 8 -2 7 - 21 -30 3 28 2 7 24 25 26 Froqu•ncy (GHz) 23 22 2. - 30 2 Figure 2: C。mparisonof Simulation and Measurements Results BK3266L BK3266L 2.3 Layout and Implementation Small changes of the antenna dimensions may have large impact on the performance. Therefore it is strongly recommended to make an exact copy of the reference design to achieve optimum pe斤。rmance. The easiest way to implement the antenna is to import the gerber or DXF file showing the antenna layout. The imported file can be used as a template when drawing the antenna. By using this procedure it should be possible to make an exact copy. If the PCB CAD tool being used does not suppo叫impo时of DXF or gerber files, Figu「e 3 and Table 1 should be used to ensure correct implementation. It is recommended to gene「ate a gerber file for compa「isοn with IFA_USB.spl when making a manual implementation. Most gerber viewers have the possibility to impo同several gerbe「 files at the same time. Thus by placing the gerber file, showing the manually implemented antenna, on top of IFA_USB.spl it is easy to ve「ify that the antenna is correctly implemented. It is also recommended to use the same thickness and type of PCB material as used in the reference design. Information about the PCB can be found in a separate readme file included in the reference design. To compensate for a thicker/thinner PCB the antenna could be made slightly shorter/longer. .

Because of the small size antenna and the small ground plane this kind of measurements is heavily affected by the presence and placement of the coax cable. This influence can「esultin a small uncertainty in resonance frequency and measured 「eflection.Typically different placement of the semi-rigid coax cable could change the resonance frequency with 5 -10 MHz and the reflection with 3 - 4 dB.
