1 Scope

This document defines the essential specifications necessary to implement the EMMY-W1 antenna reference

designs. The information contained herein and its references should be sufficient to guide a skilled person in an

attempt to implement the design on a host carrier. It will provide the designer with PCB layout details and

expected performance specifications.

The document supports the four different PCB designs for Wi-Fi:

• Two connector-based designs for the use of external antennas (one for each antenna pin of the module)

• Two designs based on SMD antennas (one for each antenna pin of the module)

This document also supports general guidelines for the design of the NFC interface.
