CRLH-TL METAMATERIAL ANTENNA

摘要

PURPOSE: A CRLH-TL(Composite Right and Left Handed Transmission Line) metamaterial antenna is provided to obtain a low resonant frequency by implementing a load on a grounding surface. CONSTITUTION: A CTLH-TL antenna(300) includes a dielectric substrate, an upper layer(311), and a lower layer(312). A dielectric substrate is located in the center of the CTLH-TL antenna. A feed line(351) and two patches(321,322) are formed on the upper layer. An interval between two patches is 0.2mm. A ground surface is formed on a lower layer. The loads(341,342) is implemented on the ground surface. The two patches and the load are connected to through a via.
