Abstract

The present invention relates to a multiband and broadband antenna, and to a communication apparatus comprising same. The present invention provides a multiband and broadband antenna, comprising: a feeder line formed in a portion of a carrier; and two or more metamaterial cells which are formed in the carrier, fed by the feeder line, and have a composite right- / left- handed transmission line (CRLH-TL) structure. According to the present invention, two or more metamaterial cells are formed, and one or more of the inductance component and the capacitance component of said two or more metamaterial cells are adjusted, thereby obtaining a multiband and broadband antenna, the length of which is determined regardless of a resonance frequency.
