The S11 parameterwas performedusinga Agilent8753DNetworkAnalyzer and BEST’S test fixturethat was usingcustomer-providingdevice. VSWR(Voltagestandingwaveratio) The VoltageStandingWaveRatio(VSWR)is an indicationof how goodthe impedancematchis. VSWRis oftenabbreviatedas SWR.If the transmissionline and the antennaare not matched,the antennawill not acceptall the powerfrom the transmissionline.The partit doesnot acceptis reflectedbackand forth betweenthe transmitterand the antenna.This sets up a fixedwavepatternalong the line whichwe can measureand whichis calledthe voltagestandingwave ration(VSWR).TheVSWR(ratioof maximumvoltageto the minimumvoltage alongthe line)expressesthe degreeof matchbetweenthe transmissionline and the antenna.When the VSWRis 1 to 1(1:1)the matchis perfectand all the energyis transferredto the antennapriorto be radiated.Whenthe VSWRis 1.5:1,96%of the powerreachesthe antenna.By definitionVSWRcan neverbe less than 1.VSWRand reflectedpowerare differentwaysof measuringand expressingthe samething.A high VSWRis indicationthat the signalis reflectedpriorto being radiatedby the antenna.

The antenna needs to be immediately placed in the testing box. The experimental period is 48 hours. During the experiment, it is not allowed to remove it midway. After the experiment, remove the antenna, clean it with cotton cloth and ion air gun, and let it dry at room temperature for 49 hours. Then, inspect the appearance, mechanical properties, and electrical properties of the antenna.
