Benefits of technology

[0009]Another object of the present disclosure is to provide an antenna that is capable of transmitting and receiving a short-wave wireless signal in a mobile terminal with a metal edge, using the metal edge thereof.
[0020]Effects of the mobile terminal according to the present disclosure are described as follows. According to the present disclosure, the 4G antenna and the 5G antenna are both realized through the sidewall portion of the mobile terminal. Accordingly, according to the present disclosure, the terminal can be prevented from increasing in size due to multiple antennas.
[0021]In addition, according to the present disclosure, a signal for the 5G communication is transmitted and received through multiple slots that are formed in the sidewall portion. In this case, according to the present disclosure, because the sidewall made of metal material is utilized for grounding, there is no need to providing grounding in order to realize the 5G antenna. Accordingly, according to the present disclosure, the 5G antenna is realized without increasing a size of the terminal.

Problems solved by technology

However, when a mmWave and an existing 4G antenna are caused to approach each other, due to mutual interference, there is a problem in which the mmWave antenna and the 4G antenna both decrease in performance.
In order to prevent this, the two antennas are positioned a distance away from each other, but there is a problem in which a size of the terminal increases.

Abstract

A mobile terminal includes a terminal main body including a circuit substrate configured to process first and second wireless signals; a sidewall portion including slits and an antenna member exposed outside of the main body so as to make up an appearance of the main body, wherein the antenna member is formed between the slits and includes multiple antenna slots; a first power supply unit extending from the circuit substrate and configured to supply power to the antenna member so the first wireless signal is transmitted and received through the antenna member; and a second power supply unit configured to supply power to the multiple antenna slots such that the second wireless signal is transmitted and received through the multiple antenna slots in a different frequency band than the first wireless signal.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of PCT International Application No. PCT / KR2018 / 005112 filed on May 2, 2018, which claims the priority benefit under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 62 / 655,212 filed on Apr. 9, 2018, all of which are hereby expressly incorporated by reference into the present application.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present disclosure relates to a high-frequency band antenna and a mobile terminal equipped with the antenna.Discussion of the Related Art[0003]Terminals may be divided into mobile / portable terminals and stationary terminals according to mobility. Also, the mobile terminals may be classified into handheld types and vehicle mount types according to whether or not a user can directly carry.[0004]Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, r...
