Abstract [en]

Metamaterials have a wide range of potential uses in areas such as optics, transmission lines, communication and RF design. The simplest metamaterial structures are composite right/left handed transmission line(CRLH TL)T-structures, Split-Ring Resonators (SRR) and Complementary Split-Ring Resonators (CSRR). Through the combination of various forms of these structures, different performances can be achieved.

In this thesis depth investigation was performed on a metamaterial transmission line that was realized through microstrip filter using composite right/left-handed transmission line (CRLH TL) metamaterials. The filter was designed in the band, Railways GSM-900 (915.4 MHz – 921 MHz), and then compared with the conventional filter, because designing a metamaterial filter is simple with considerable size reduction and improved  results.

In this thesis the behavior of different parameters and their impact on the filter performance is also investigated.

Different filters were designed by using different substrates  including Rogers 5880 , Rogers 3010, Arlon 25 FR, and FR4 having different dielectric constant, thickness and loss tangent to see their impact.

Finally, a band pass filter was designed at required frequency(915.4 MHz – 921 MHz)  through EM- simulation. The simulated values are presented and show  required results.

Metamaterial filters are useful in many communication applications because they have compact size, low loss, good performance and are cost effective.
