AntennaCharacteristics8.1 Antenna SelectionThe WT1SBSL supports on-board PCB printed antenna.When the Operating Frequencyisbetween 2.4G~2.5GHz, S11 of antenna port is less than-10dB and peak gainis about 1. 5dBi.Figure 7. Antenna radiation pattern simulationFigure 8. Antenna port S11simulation curveIn practical use, 3328-P is welded on user’s boardand value of S11 has some changes.
15www.ibroadlink.com8.2 Minimizing Radio InterferenceWhen integrating the Wi-Fi module with on board PCB printed antenna, make sure the threepoints below:1. The area under the antenna end of the module should be keep clear of metallic components,connectors, vias, traces and other materials that can interfere with the radio signal.2. The area around the antenna end the module protrudes at least 10mm from the motherboard PCB and any metal enclosure.3. When planning PCB layout, it is recommended that user places the antenna of Wi-Fi moduleas close as possible to the edge of boarder to ensure the good performance of antenna, whichis shown in the picture below.8.3 Specification of On-Board AntennaOperatingFrequency2.4G~2.5GHzVSWR(max)2Peak Gain1.5dBiAntennaTypePIFA
