Question

Hello,

we are working on a quite dense design and we have a question about track shape. Can it be curved and can this antenna be places on the top center of the PCB?

Here we have an 8 layer design with Ublox module, LNA and Pi network with 0201 matching components:

Answer 1

Hi,

The antenna needs to be placed on the left corner of the PCB with Pin 1 facing the left side similar to the placement in our EVB. The transmission line can be curved but straight is ideal, try minimise the amount of curves as much as possible but it will still be better than 90 degree angle lines.

May I ask what size PCB are you working with?

Best regards,
