locate, communicate, accelerate 3 General description When using the LILY-W131 together with this antenna reference design, the circuit trace layout must be made in strict compliance with the instructions below. All the components placed on each RF trace must be kept as indicated in the reference design. The reference design uses a micro coaxial connector that is connected to the external antenna via a 50 Ω pigtail. 1 2 Figure 1: Antenna Reference design embedded in a host carrier PCB Reference Description 1 Host carrier PCB (light green) 2 Antenna connector reference design (darker green) Table 2: LILY-W131 and host carrier PCB.

The solid GND layer beneath the ‘top layer’ shall be minimum 19x15 mm according Figure 4. No traces are allowed to be routed on the GND layer within this area but vias and small openings are allowed. The minimum size of the top layer GND plane is marked in Figure 4 and no other components are allowed within this area.
