Supplementary information

Trace layout and dimensions including specific designs for each type:

  1. Layout of trace design, parts, antenna, connectors, and isolation requirements:
  2. 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

: 0.33*0.33mm

Note:

  1. RF trace between module RF pinout to antenna width is 0.8mm.
  2. RF trace between module and antenna impedance is 0 ohm.

IPEX connector information

Size:

  1. Different antenna length and shapes effect radiated emission and each design should be considered a different type:
