Abstract

The invention discloses an antenna apparatus and electronic equipment. The antenna apparatus comprises an antenna, a first grade circuit unit and a matching unit, wherein the first grade circuit unit comprises one inductor; the inductor possesses a first end and a second end; the first end is connected to the antenna; the matching unit possesses a third end and a fourth end; the third end is connected to the second end and the fourth end is grounded. When the electronic equipment needs to receive or send a first signal, the first grade circuit unit generates a first current corresponding to a first current frequency of the first signal so that the antenna and a metal plate which is connected to the antenna and is arranged in the electronic equipment generate resonance under an effect of the first current; a first radiation signal corresponding to the first signal is generated so that the first signal is received or sent by the electronic equipment.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an antenna device and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic equipment has also been developed rapidly and has become a necessity in people's daily life. In order to meet the needs of users, electronic equipment has more and more functions, so that the structure of electronic equipment becomes more and more complex, so that the space occupied by the antenna in electronic equipment becomes smaller and smaller; and in the communication of electronic equipment When the frequency band is in the low frequency band of 700-960MHz, the wavelength of the electromagnetic wave is relatively long. In order to make the antenna resonate, the length of the antenna must reach at least 1 / 4 of the wavelength of the electromagnetic wave, which forms a huge gap with the antenna space that current electronic equipm...
