ASYMMETRIC COPLANAR WAVEGUIDE ANTENNA USING COMPOSITE RIGHT/LEFT-HANDED TRANSMISSION LINE AND GROUND PLANE

摘要

The present invention provides an antenna comprising: a first grounding part formed on one layer of a substrate; a composite right/left-handed transmission line (CRLH-TL) part formed on one layer of the substrate and connected to the first grounding part; a second grounding part formed on another layer of the substrate; and one or more vias for connecting the CRLH-TL part to the second grounding part, wherein resonance is generated by the CRLH-TL part and the second grounding part. According to the present invention, an antenna having a broader band than a metamaterial antenna can be realized and a small-sized antenna having a broad bandwidth can be realized.
