All rights reserved. Yanzi is a brand of Altacogni AB Layout and general design recommendations While designing the PCB using Yanzi stamp module make sure to keep all the layers beneath the 12mm of 2.4GHz antenna area free of any planes or traces. Avoid routing on the first (top) layer of the PCB laying under the Yanzi stamp PCB area. It is important to keep ground planes and any isolated metal parts (such as screws) away from both 2.4GHz and sub-GHz antennas. Antenna facing outwards and facing away from wall is preferred while designing the product. It is always a good idea to keep the polarization of antenna equal between the sensor products and the access point or gateway for best performance although it is not a must.
