Design of Compact Composite Right-Left-Handed Transmission Line Unit Cells
نویسندگان
چکیده
A new unit cell composite right/left-handed (CRLH) metamaterial using microstrip technology with coupled line is proposed. It is simple and has a small size. The proposed unit cell can be designed in several frequency bands based on its geometrical parameters. The transition from LH to RH shows the balanced condition without the presence of stop band. Two designs for two different frequency bands have been carried out. The frequency band of the first design is about 320 MHz and the band of the second design is about 1.3 GHz. This unit cell is fabricated and its measurement results are shown. Good agreement has been achieved between the theoretical and the experimental results.
