I'm trying to embed a u-blox neo6m gps module to an stm32 controlled board. I'm planning to connect the module to an SMA connector and use a 50ohm antenna.
The datasheet of the neo6m states that the impedance of the connection between the module and the antenna must be 50ohm. The datasheet only contains info about the microstrip impedance matching method. However, all the schematics I found online implement LR networks to match the impedance. An example is below,
My questions are: Can I use any of the two methods to match the 50ohm impedance?
Also, if I used the L-network method, would there be anything specific(trace dimensions, planes under the network etc.) I'd need to do when routing the network to the antenna and the module?
Finally, does any of the two methods have advantages over the other? If so, what are they?
