Holux UB-93 GPS module and GPS active internal antenna

Hi everyone !
I'm a student and I currently working on my project. One part of my project is to build a GPS board based on GPS module. I bought a Holux UB-93 GPS module and a GPS active internal antenna (similar to these antennas ). I started to design my GPS board but now i got stuck. UB-93 specification indicate that UB-93 need an antenna (active or passive) to operate but it didn't mention how to connect an active antenna to UB-93. I read in this specification that pin 18 and 19 are used to interact with active antenna only but i don't know how to use those or their functions ?
This is my first time working with GPS and i really need advices or documents from whoever know about GPS and GPS antenna.
Thanks everybody !

1. Using External or Internal antenna: You can use external or internal antenna for GPS module. I had tested with both antenna and the result is very good.

2. Schematic interface between UB-93 GPS module and microcontronller:

Note: You can use external or internal antenna with this schamatic.

3. How to extract datas from GPS with microcontroller:
EX data: SGPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,1 30694,004.2,W*70

4. PCB Layout Recommandation for RF signal
