Abstract

The invention discloses an antenna device and a mobile terminal. The antenna device comprises an antenna conductor, wherein the antenna conductor is provided with a radiation pattern, the radiation patter is provided with a first structure part, a second structure part, a third structure part and a fourth structure part, a first gap part is formed between the first structure part and the second structure part and is used for gap coupling, a second gap part is formed between the third structure part and the fourth structure part and is used for gap coupling, the fourth structure part is connected with the second structure part, the second structure part and the fourth structure part are divided by a feed unit, and a hollow hole is formed in the second structure part. By the antenna device, the technical problem how to form more resonance by arranging branches, gaps and the feed unit is solved, and a specific absorption ratio (SAR) value of an antenna is effectively reduced by holes formed in the branches.

Description

technical field [0001] The present invention relates to antenna technology, and more specifically, to an antenna device and a mobile terminal. Background technique [0002] Antennas are important components in mobile terminals such as mobile phones. The antenna is an important factor affecting the communication quality of the mobile terminal. [0003] figure 1 A schematic diagram of the interior space of the mobile phone is shown. Due to the setting of metal parts such as USB or MIC connectors, the headroom area inside the mobile phone is reduced, and the spacing is set, for example, in figure 1 Among them, there are three clearance areas on the circuit board in the mobile phone, namely: a first clearance area 201 , a second clearance area 202 , and a third clearance area 203 . In the second clearance area 202, a ground point 205, a feed point 206, and a ground point 204 are arranged in sequence. [0004] figure 2 An example of the antenna device in the above environm...
