Problems solved by technology

However, the general tunable antenna (Tunable Antenna) currently being studied uses a switch (Switch) to open more than two frequency bands, or uses a variable-cap (Variable-cap) to only use the frequency sweep (sweep) function, there is an overall Disadvantages of narrow tunable range (Tunable Range)
This tunable antenna has certain limitations in meeting the sufficient resonance length of the antenna in a limited space.
[0009] In addition, in the case of using low-frequency broadband and carrier integration (CA: carrier aggregation) of another frequency band at the same time, since both frequency bands are used, there is a problem that tunable or switchable antennas cannot be used

Abstract

A mobile terminal, according to the present invention, comprises: a first conductive member that forms a part of a lower end of an outer metal frame; and a second conductive member that is spaced apart from the first conductive member and that forms a part of the lower end and a side surface of the outer metal frame. In addition, the mobile terminal may additionally include conductive lines that are respectively connected to points on the respective first conductive member and second conductive member, and that are connected to one another inside the mobile terminal. To this end, the second conductive member is adjacently connected to ground in a certain location from the point on the second conductive member, and thereby an antenna apparatus and a mobile terminal that can cover all low-frequency bands including LTE, and that have a hand effect correction function can be provided.

Description

technical field [0001] The present invention relates to a mobile terminal with an antenna device for transmitting and receiving wireless signals. In more detail, a mobile terminal with a broadband antenna. Background technique [0002] Terminals can be classified into mobile / portable terminals and stationary terminals according to whether they can move. Mobile terminals can be classified into portable terminals (handheld terminals) and vehicle mounted terminals (vehicle mounted terminals) according to whether users can carry them. [0003] Functions of mobile terminals are being diversified. For example, there are functions for data and voice communication, taking pictures and taking videos through a camera, recording audio, playing music files through a speaker system, and displaying images and videos on a display section. Some terminals can additionally play electronic games, or perform multimedia playback functions. In particular, recent mobile terminals can receive m...
