    Hello Harald,

    I am working on an M2M design and I would like to integrate GSM/UMTS on the same PCB with WiFi and BLE. I am interested in more design details on your GSM antenna design and also any tips you may have regarding integration of the other wireless technologies.

    Thanks.

    Hello Harold,

    I am working on a compact portable M2M design. Ultimately I would like to put the antenna into a flex strip in the top cover of my thin enclosure. I would love to see more details on your design and any tips you might have for this non-RF experienced engineer!

    Thank you Harold,

    Tom

    Hello Tom,
    I will send you an offer for my IoT M2M Cookbook. Table of contents:

    Tom, you have to understand the antenna basics descriped in the book, before you go ahead. I assume that your device is for US market. In you US you will have PTCRB with its tests on TRP and TIS.
    Regards
    Harald
