Question

Hello,

We are a company from Turkey, Ankara. We decided to use your antenna in our products. We use U-blox Lara-R211  LTE modem. I designed a board and have tested it currently. I think our design has poor antenna performance. Can you guide us for better performance?

Thank you. I look forward to hearing from you soon.

Best Regards

Answer 1

Hi Fatith,

We recommend a CPW to best control the feed impedance and you should have a nice solid ground plane behind the antenna (i.e. below it, in the image). Also we'd need to see the full gerber to look at all the layers of your PCB to give complete guidance. I've passed your details on to your regional representative who will be in touch soon to give you a fully tailored response.

Many Thanks

Steve

Hi Steve,

Thank you for your quick response. I added gerber files.
