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) thematch 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. 驻波VSWR Marker2400MHz 2450MHz 2500MHz S.W.R<3.0 Product Number ： SC2400D1(D1W2)-L300 Page 4 Version：1.0Issue Date 2024-3-6 4.测试3D报告 频率：2400MHZ增益：3.11dbi 频率：2450MHZ增益：3.52dbi 频率：2500MHZ增益：3.84dbi Product Number ： SC2400D1(D1W2)-L300 Page 5 Version：1.0Issue Date 2024-3-6 5.
