dB 5 Version1.0.0 TYBT2 ,TYBT2-IPEX UserManual 5.Antenna Information 5.1 Antenna type Antenna for TYBT2 module is using On-board PCB antenna Antenan for TYBT2-IPEX module is using IPEX connector Antenna 5.2 Reduce Antenna Interference In order to have the best RF performance, Its recommended to keep a minimum 15mm distance between the antenna part and the other metal pieces. Since PCBA manufacture use SMT process to weld TYBT2 module and other electrical components onto the PCB board, RF performance will depend on the layout location and pattern of the On-board PCB antenna. The following figures are some recommended and dis-

recommended demonstrations from out R&D team. In demonstration 1 and 2 of figure 3, the on-board PCB antenna lays outside of the PCB frame. Its recommended to use layout pattern shown in demonstration 1 and 2. Either the on-

board PCB antenna lays outside of the PCB frame directly or PCB frame carve out a certain area for the antenna. The overall PCBA performance for these two ways will be the same as testing the module independently. Restricted due to some reason, if the on-board PCB antenna layout has to be inside the PCB frame, its suggested to refer to demonstration 3. The antenna lays inside the PCB frame, but no copper or wire beneath the antenna. RF performance will have some loss, approximately 1~2 dBm. Its NOT recommended to use demonstration 4, the antenna lays inside the PCB frame, and there are copper and wire beneath it. RF performance will have significant attenuation.
