I just checked out the Google Analytics report and not only do I have views from America (the main source), but also from West Vancouver, Canada, and Perth, Australia! I'm going global! ;)
Aside from my global popularity, I have run into a 5 foot tall speed bump. I'm working on making my pcb for the LEA-5H gps module from U-Blox, and when reading the hardware integration manual, the difficulty of this step hit me. Everything is so specific and sensitive, making this board is going to be a pain.
I'm currently wanting to have the Open circuit detection and short circuit detection circuitry on the board, as well as a SMA port for this antenna to plug into, and a usb port, and then the I/O to the main Propeller board.
If anybody already has something like this, or wouldn't mind helping in the construction, it would be greatly appreciated if you'd let me know.
P.S: What's the point of all the "holes" on the PCB as seen here, I have seen them on a number of boards and am baffled by them.
**Edit (8/4)**I contacted Peter Miller, over at Petermillerphotos.com, and he told me that the holes are to improve the ground plane of the antenna. He also gave me a few tips on the microstrip and its resistance, he suggests that in order to get the correct 50 ohm resistance, I should use a 4 layer pcb.
