The one on the right is WIFI, the one on the left is GPS I believe That antenna only picked up Linksys barely, and would sometimes pick up the Bebe barely. This one, even though it was horribly constructed, did better than the Collinear antenna I used first. My P1SS-poor quickly hacked up Double Biquad antenna. See, my soldering isn't bad when I have something to solder to that my iron can actually heat up! Even with this 14g wire, I still had to sit the antenna on the iron for several minutes for it to heat up. A Single Biquad and a Double Biquad with the ground plane. If I was using a properly built antenna you can only imagine what kind of signal increase could be achieved.Īnd here are the new antennas in development. I did manage to see some impressive results. The foil was bent and curved and I was trying to hold the antenna and the foil in place while aiming it at a neighbor's access point while holding the connection in the plug on the BB's board and hitting "scan for networks". The distance from the antenna element and the ground plane needs to be precise at exactly 17mm. I did manage to get it to stick but didn't put the ground plane on first so I just used some tin foil for this test. I used too heavy of wire (10g) for the first one and was unable to properly solder it. I am building a Double Biquad directional antenna. I wanted to test a stronger antenna for this project. I believe the outer ground of this plug acted as a ground plane. If I had a ground plane I could have gained more signal and reduced noise. When using this antenna, I gained reception and didn't use a ground plane. The antenna I have in this picture is an Omnidirectional Collinear Sectional Antenna made from 18g or 22g copper wire with one end filed down to a taper to fit in the plug's hole. The outer of this plug is the antenna ground. This connects directly to the WIFI module's antenna pins, and by connecting an antenna to the center pin, you can increase WIFI signal. There is a test plug below these terminals that is used for radiation emissions testing and for technicians to test the WIFI module. By doing this, the built in antenna cannot interfere with a new external antenna. Scotch tape has been placed over the terminals where the antenna makes contact to. This is what the phone looks like completely taken apart:Ĭloseup of the PCB for EDGE cell service on T-Mobile Currently I am waiting on some W.FL, U.FL, and MC Card connectors to mount to the case so an antenna can be attached through a drilled hole. I have also found a simple way to disable this antenna and connect an external antenna with no soldering to the board required.

HOME MADE DOUBLE BIQUAD WIFI ANTENNA TRIAL
I am not this skilled, my hand is not steady enough, and I do not have the proper soldering iron and solder.Ģ.) You will void your warranty by taking apart your phoneģ.) There is a good chance you will break your phone to the point that it is unrepairableĤ.) This is not a beginner project and knowledge of proper electronics handling is needed.ĥ.) A static free environment is a must as any static discharge from you to the board can destroy it.Īfter much trial and error, I have officially found where the WIFI antenna is located in the Blackberry 8820. It would take a very highly skilled expert at soldering to solder to where the antenna connection is located. It is a heat sensitive multi-layered sandwiched board and any heat will ruin it. I'll buy a new one and turn my old one into a development board or something else cool like that!ġ.) Do not solder to the board. Personally, I don't care much if I break it. Even if you know what you are doing, you probably should not be messing with it like I did unless breaking your phone is not a big deal to you. If you don't know what you are doing, you will most likely break your phone.

There is no way around it, there will be signs that it has been opened. By opening your phone, you will most likely instantly void your warranty. Before you read on, you should understand the risks of doing what I have done with my phone.
