FCC ID: 2A8C3-BT52 RF Exposure Evaluation REQUIREMENT KDB447498 D01 General RF Exposure Guidance v06, Clause 4.3.1(a) [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 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 test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion. TEST RESULT Passed Not Applicable Type Channel(MHz) Conducted Power (dBm) Maximum Tune-up (dBm) Calculating data Limit Result BT BLE 00 0.83 1.00 0.3902 3.00 Pass Note: 1) The maximum antenna gain is -1dBi 2) The exposure evaluation safety distance is 5mm.

ANT-004-2G4 1、 Abstract ANT-004-2G4 is a PCB antenna for 2.4GHz portable devices such as Bluetooth and WiFi. 2、 Outline 3、 Frequency 2402-2480MHz 4、 Performance Parameter Size Parameter Frequency SW R 2402MHz <1.7 2460MHz <1.7 2480MHz <1.7 Smith chart Frequency Gain(max ) 2400MHz -2dBi 2460MHz -1dBi 2525MHz -1dBi SWR Chart XOY Planar antenna gain diagram Frequency Gain(max) 2400MHz -1dBi 2440MHz -1dBi 2525MHz -1dBi XOZ antenna gain diagram YOZ antenna gain diagram 5、 Notes The antenna is sensitive to the size of the PCB RF ground layer and the plastic shell of the product. The antenna can be modeled as an LC resonator whose resonant frequency decreases when L(inductance) or C(capacitance) is increased. Larger radio frequency layers and plastic enclosures increase the effective capacitance, reducing the resonant frequency. Adjust the matching parameters according to the actual installation situation. Frequency Gain(max ) 2400MHz -2dBi 2460MHz -2dBi 2525MHz -2dBi
