Trace layout and dimensions including specific designs for each type:
- Layout of trace design, parts, antenna, connectors, and isolation requirements:
- Boundary limits of size, thickness, length, width, shape(s), dielectric contain, and impedance must be clearly described for each type of antenna:
PCB Antenna trace antenna Dimension
Note: all distance is 0.3mm.
Dipole antenna dimension
u.FL connector information: Manufacturer: HIROSE ELECTRIC; Size:
Note:
- For Antenna selection, PCB antenna and dipole antenna only can choose 1 type.
- RF trace between module RF pinout to antenna width is 0.4mm.
- all R/L/C Component’s width is 0.5mm, length is 1mm.
- RF trace between module and antenna impedance is 50ohm.

Layout guide of RF trace for the trace antenna
PCB requirement: The dielectric constant of PCB is 4.6, and the impedance
boundary is limited to 0.5mm. The thickness of RF trace copper is 48um, and
the total thickness of base plate is 1.6mm.
Matching
RF matching
Different antenna length and shapes effect radiated emission and each design should be considered a different type: 2.4G WIFI:
