How to make a wifi antenna Source：eahison Have you lost your WiFi antenna? Most WiFi NIC antennas can be removed and are therefore easily lost. In fact, with just a few household items, you can make a practical WiFi antenna as a replacement, enough to support the day you buy a new antenna. If the wireless network is not wide enough, you can also make a directional antenna to expand the effective range of the wireless network.
Make a paper clip antenna 1. Prepare the materials and tools. big paper clip, used old ballpoint pen, electrical tape. straight ruler, scissors, lighter. 2. Straighten the paper clip. Unfold the paper clip and straighten it into a straight shape. 3. Measure and cut the paper clip. For the best signal, the paper clip length as close as 61 mm, only this is the way to make the most efficient Wifi antenna. 4. Bend the paper clip. You need to bend the paper clip at approx. 19 mm to form a 90° right angle. This part of the paper clip will be inserted into the WiFi antenna in the port. 5. Remove the ballpoint pen refill. You'd better use an abandoned ballpoint pen because you need to cut the refill. Cut the refill into a length of 12-18 mm. Due to there may be ink in the refill, so cut the refill away from yourself. When cutting, you can place the refill on a flat surface to prevent ink from splashing on your body. 6. Place the refill over the bent portion of the paper clip. Place the refilled part of the refill over the bent corner of the paper clip. Make sure the cartridge is approx. 1.5 mm beyond the end of the paper clip. 7. Use a lighter to shrink the refill. Use a lighter or other heat source to carefully heat the refill on the paper clip. This will cause the refill to shrink so that it fits tightly over the paper clip 8. Insulate the antenna. Wind electrical tape around the paper clip to prevent interference from wireless signals. 9. Insert the paper clip into the antenna port. Insert the “refill” of the paper clip into the antenna port to ensure that the interface pins are connected to the paper clip inside the cartridge. Such as if you can make them overlap, then the received signal will be better.
