ABSTRACT:
Disclosed is a 3D inverted F-antenna for easy production, fast assembly, wider bandwidth that provides excellent capacity of radiating and receiving wireless signal inside wireless communication devices. The 3D inverted F-antenna includes a ground plate. A radiating plate has a hole wherein the dimensions of the radiating plate and the hole are decided by ½ of the predetermined resonance wavelength. A shorting unit is connected to the ground plate and the radiating plate. A media is located between the ground plate and the radiating plate for isolating the ground plate and the radiating plate. A conductive signal feeding device is located in the ground plate and electrically coupled to the radiating plate for transmitting signal.
