Users can modify the antenna type with the method below but MXCHIP would not take any responsibility for this behavior. EMW3166 loads the resistance (0Ω/0402) in the red box, it means user can use PCB antenna. If user wants to use U.F.
PAGE 23
Datasheet [Page 22] the module protrudes at least 15mm from the mother board PCB and any metal enclosure. If this is not possible use the on board U.FL connector to route to an external antenna. 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. Minimum size of keep-out zone around antenna： Figure 9 Antenna minimum clearance zone 4.3 U.F.L RF Connector This module use U.F.
