Problems solved by technology

[0020] Since the antenna applied to a conventional mobile phone is implemented in a single mode regardless of its frequency mode (that is, regardless of whether its frequency mode is a single-band mode or a multi-band mode), each band is not only independent in mute performance and independently on the antenna radiation characteristics
To address these issues, antenna gain can be increased to improve quiet performance, however, this leads to the side effect of increased Specific Absorption Rate (SAR)

Abstract

A multi-band antenna for a mobile phone is provided. The mobile phone includes a multi-band antenna which is mutually connected in a dependent manner for operation according to a signal transmitted to and received from the mobile phone; and a resonance unit for generating resonance for multiple frequency bands as ends of the multi-band antenna are spaced apart at a predetermined interval, to improve mute performance, reduce SAR, and prevent a reduction in call performance due to an influence of a user's body and hand when holding the mobile phone to make a call.

Description

technical field [0001] The present invention relates to an antenna for communication, in particular to a multi-band antenna applied to a terminal (for example, a mobile phone). Background technique [0002] With the recent rapid development of mobile communication and satellite communication technologies, wireless communication in the information society is becoming more and more important. Wireless communication technologies originating from voice-oriented narrow-band communication are rapidly developing into wide-band communication for the Internet, multimedia, and the like. [0003] Commercialization of new wireless services such as 4th generation mobile communication and high-speed mobile communication based on IMT-2000 is imminent. Antenna technology is the main technology that forms the basis of wireless communication, and since the antenna performance of mobile phones is a factor that determines the quality of communication, the importance of antenna technology is in...
