DS70005557C - 21

Table 2-3. PCB Antenna Specification for WILCS02 Module

Parameter

Specification

Operating frequency

2400-2485 MHz

Peak gain

1.18 dBi at 2445 MHz

Efficiency (average)

68.83%1

Note:

1. The size of the WILCS02 Wi-Fi® Link Controller SD Board is 85 mm x 40 mm. The antenna efficiency will improve with

larger ground plane baseboards. If the best case routing guidelines are followed on a larger ground plane application

board, the efficiency will be better.
