I want to interface the WISMO218 GPRS chip with an antenna. The antenna lines on the PCB board have to be very specific, otherwise the system won't work. I have uploaded the part of the datasheet that refers to the antenna.
I am going to use an antenna and and a coaxial jack as seen at the links below:
My PCB board is of the type "FR-4", Copper thickness: 35um, Height of the board: 1.6mm
I would like to interface the antenna on the same way as seen at the datasheet.
How can I calculate the line width, and the distance from the ground planes in order to achieve the 50 ohms impedance? Only the top layer is going to used for the antenna.
Remember that this operates in high frequencies.
Thanks in advance
The data sheet states the following:
