-1 METAMATERIAL -1 MODE ANTENNA IMPROVED BANDWIDTH AND EFFICIENCY

摘要

The present invention relates to a metamaterial-1 mode antenna with improved bandwidth and efficiency. The metamaterial-1 mode antenna improved the bandwidth and efficiency according to the present invention is a ground plane having a rectangular flat plate shape and serves as an antenna patch. The metamaterial-1 mode antenna has a square shape and is formed parallel to the patch plane 1, a second patch surface; And first and second via portions formed between the ground plane and the first and second patch faces to form a mushroom structure. The present invention improves the bandwidth and efficiency by theoretically calculating the dispersion curve of the CRLH transmission line. Also, according to the present invention, by analyzing the metamaterial-1 mode antenna theoretically, it is easier to downsize than the conventional antenna, and the bandwidth and efficiency can be improved.
