My office is located below the ground level and therefore GSM reception is not satisfying so I am using a simple 4G Antenna placed outside where the signals are strong enough.
The antenna wire is on my desk and I keep the phone close to it. Simple, but it works, I can get my SMS instantly without having to go up with the phone.
I would like to build a cradle and connect the SNA connector to a PCB which most of it would be a copper plate that will be located underneath the phone.
My question is how to design the copper plate, should it be grounded, and how, should it be spiral or flat? any other considerations?
Here's several inner antenna designs, remember that the phone back side would be flat with the antenna PCB. Which of the designs, if any, makes sense for this particular need?
Thanks!
