How To Make A Wireless FM Antenna For Any Mobile Phone

Today I'll tell you how to make a wireless FM antenna for any mobile phone which have 3.5mm earphone jack.

Step 1- Take any cheap 3.5mm earphone(which you could destroy!).

Step2- Cut the earphone wire from from top of the pin.

Step3- Take the pin and remove all plastic insulation attached to it.

Step4- Take a small length of copper wire(about 10-12cm long).

Step5- Attach one end of the copper wire to the top pin of the jack, if you want,you can solder it also. Now connect the jack to your phone and open FM radio,tune in to your favorite channel. Depending on the signal strength at your house,your phone should catch FM signal.

Step6- Your FM antenna is ready, you can attach other end of the wire to the pin above the flat pin,as shone in the figure below. That will make a loop.



Step7- If you want,you can cover the portion above flat pin with tape or thread for grip and for decoration,as I did.
