4.2 2-Layer Trace Antenna Design
2.4 GHz Chip Antenna Implementation
When using the certified Chip Antenna (Johanson Part Number 2450AT18A100), the PCB
layout shown in Figure 16 should be followed. It is acceptable to keep the U.FL circuitry J7 and
J8, and the U.FL connectors can either be populated or not.
2.4 GHz Dipole Antenna Implementation
When using the certified 2.4 GHz Dipole Antenna and U.FL to RPSMA Cable, the PCB layout
shown in Figure 17 should be followed. Components J7 and J8 should be populated as shown
in the schematic.
2.4 GHz FlexPIFA Antenna
When using the certified 2.4 GHz FlexPIFA Antenna w/U.FL cable, the PCB layout shown in
Figure 17 should be followed. Components J7 and J8 should be populated as shown in the
schematic.
