The S11 parameter was performed using a Agilent 8753D Network Analyzer and BEST’S test fixture that was using customer-providing device. VSWR (Voltage standing wave ratio) The Voltage Standing Wave Ratio (VSWR) is an indication of how good the impedance match is. VSWR is often abbreviated as SWR. If the transmission line and the antenna are not matched, the antenna will not accept all the power from the transmission line. The part it does not accept is reflected back and forth between the transmitter and the antenna. This sets up a fixed wave pattern along the line which we can measure and which is called the voltage standing wave ration(VSWR).The VSWR (ratio of maximum voltage to the minimum voltage along the line)expresses the degree of match between the transmission line and the antenna. When the VSWR is 1 to 1(1:1) the match is perfect and all the energy is transferred to the antenna prior to be radiated. When the VSWR is 1.5:1, 96% of the power reaches the antenna. By definition VSWR can never be less than 1.VSWR and reflected power are different ways of measuring and expressing the same thing. A high VSWR is indication that the signal is reflected prior to being radiated by the antenna.

Product Appearance 一、Salt Spray Test Test objective: Test antenna resistance to salt spray corrosion Test method: Concentration of solt solution: 5% sodium chloride solution (95 ml distilled water + 5 g sodium chloride) Place the antenna in the salt spray test chamber and suspend it with a rope to ensure uniform solution application and to avoid any uncoated areas on the antenna surface. After spraying the solution, immediately place the antenna in the test chamber. Set the experimental duration for 48 hours, during which the sample must not be removed. At the end of the experiment, take out the antenna and clean it with a cotton cloth and an ion blower to ensure all residues are removed. Allow the sample to dry at room temperature for 49 hours. Product Number： FLK-2.4GAOB Page 6 Version：1.0 Issue Date2024-9-27 Finally, inspect the antenna's appearance, mechanical properties, and electrical performance. Test Report Approval Verified Mr.Dai Test Operator Mr.Yang Sample: 2.4GHz Antenna Test objective: To evaluate the changes in the antenna's appearance, mechanical properties, and electrical performance under salt spray conditions. Sample Q’ty: 5pcs Before Test Sample No. Appearance Mechanical properties & Electrical performance 1# OK OK 2# OK OK 3# OK OK 4# OK OK 5# OK OK After Test Sample No. 1# OK OK 2# OK OK 3# OK OK 4# OK OK 5# OK OK Conclusion: The salt spray test has been completed. The antenna's appearance is acceptable, and it maintains a good connection with the main board, as confirmed by continuity testing with a multimeter. No changes were observed in the mechanical properties. Signal testing showed that the standing wave ratio varies within ±0.3, which meets the permissible requirements. Therefore, the 2.4GHz internal antenna complies with the salt spray test criteria.
