Problems solved by technology

[0006] However, the antennas proposed above are dependent on the resonant frequency, so they cannot exceed the limit that determines their size. The smaller the size of the antenna, the more complicated its shape is to form an antenna with a fixed length in a narrow space.

Abstract

A multiband and broadband antenna using metamaterials and a communication apparatus comprising same are provided. According to one embodiment of the present invention, provided is a multiband and broadband antenna, comprising: a feeder unit formed in at least a portion of a carrier; and at least one double negative (DNG) unit cell which is formed in the carrier, fed by the feeder unit, and serves as a composite right / left handed transmission line (CRLH-TL).

Description

technical field [0001] The invention relates to an antenna and a communication device including the same. By using the properties of metamaterials, the size of the antenna is further miniaturized, and the resonant frequency is easier to adjust, so that multi-band and wide-band can be realized. Background technique [0002] With the advancement of the electronic industry and the high development of communication technology, especially wireless communication technology, various wireless communication terminals that can perform voice and data communication with other people anytime and anywhere have been developed and widely popularized. [0003] Moreover, in order to improve the portability of wireless communication terminals, various technologies aimed at miniaturization of wireless communication terminals are being studied, such as the development of large-scale integrated circuit components, electronic circuit board miniaturization methods, etc., and the purpose of use of wi...
