antenna specification antenna size is 11.20mm*5.5mm From below Specification. Please refer to the chart below for PCB size of RF line terminal.
1) 2) Antenna clearance area: there shall be no copper foil routing (package) directly below the antenna area of the user's motherboard(Including power supply, ground and signal layer). Module position: ideally, the module should be arranged in a corner of the user's motherboard, PCB The antenna is located far from the motherboard End. This position minimizes the clearance area of the antenna.
C1a is the antenna matching capacitance, which affects the signal strength.
FCC Statement FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247 Trace antenna PCB antenna , Antenna gain 0dBi This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. 2.
