It is a problem of improving the antenna. This will only help on distance. Cell phones reduce the power output when close to a tower. The cell phone is optimized for the antenna they are using and it will do no good to just change the antenna. Your best bet is to make a reflecting dish and to focus the output to a smaller angle. Then all the power that you put out will go in the direction you point the dish. The receiving ability will also increase by having a larger capture area of the dish.

Building a cell phone signal booster out of a copper sheet is possible, but it requires some technical knowledge and understanding of the theory behind it. Here are the basic steps to build one:

1. Gather Materials: You will need a copper sheet, a coaxial cable, an antenna connector, a power supply, and a soldering iron.

2. Cut the Copper Sheet: The first step is to cut the copper sheet into a rectangular shape with dimensions of 6 inches by 4 inches.

3. Create the Antenna: Using a soldering iron, create a dipole antenna by soldering a coaxial cable onto the copper sheet. The length of the cable should be 3 inches on each side of the sheet.

4. Connect the Antenna to the Phone: Connect the antenna to the phone using an antenna connector. If your phone does not have an antenna connector, you can use a cell phone signal booster kit that comes with an external antenna.

5. Connect the Power Supply: Connect the power supply to the antenna using the coaxial cable. The power supply will provide power to the antenna, which will amplify the cell phone signal.

6. Test the Signal Booster: Once everything is connected, test the signal booster by making a call. You should notice an improvement in the signal strength.

The theory behind this is that the copper sheet acts as a reflector, bouncing the cell phone signal towards the antenna. The antenna then amplifies the signal and sends it back to the phone, resulting in a stronger signal.

It is important to note that building a cell phone signal booster out of a copper sheet may not be as effective as using a commercial signal booster. It also requires technical skill and knowledge, so it is recommended to seek professional help or use a commercial signal booster for better results.
