Is recertification necessary?<\/h1>\n\n\n\n

Q: I have a question for you. It can be assumed that my new product contains a certified GSM module and is connected to a PCB antenna I developed. If my device is to receive CE certification, does it need to be fully re-tested? Will my custom PCB antenna cancel the wireless module certification?<\/p>\n\n\n\n

Answer about certification and antenna<\/h2>\n\n\n\n

A: The CE (RED) certification only applies to the radio module and is not transferred to the complete circuit board and enclosure. CE +CE \u2260 CE. You will have to test the final configuation, but only a subset of the tests already passed by the GSM module on its own.<\/p>\n\n\n\n

With a badly designed antenna with a high Return Loss, harmonics can be generated quickly. Also, even a good chip antenna that is incorrectly integrated, for example with a ground plane that is too small or with a poor layout may also lead to harmonics.<\/p>\n\n\n\n

If you don\u2019t have any experience or measurement equipment (Vector Network Analyser), it is difficult to evaluate a self-made PCB antenna. If you are lacking experience then we recommend using an external antenna consultant. A consultation with report often costs only 3 to 4 hours working time and saves thousands of Euros in repeated attempts at radio certification.<\/p>\n\n\n\n
