A METAMATERIAL-EMBEDDED WIDE-BAND ANTENNA FOR THE MICROWAVE C-BAND

In this paper a metamaterial-embedded, compact microstrip-fed patch antenna is introduced for microwave C-band applications. The proposed antenna is composed of a rectangular metamaterial-embedded patch, microstrip-fed line and a partial ground plane. The finite-integration technique (FIT) based on Computer Simulation Technology (CST) Microwave Studio is utilized in this study. The measurements of antenna performances are conducted in a near-field measurement laboratory. The antenna performance parameters comprising the reflection coefficient, radiation efficiency, gain, and radiation pattern are studied to validate the antenna performance. The measured results show that the proposed metamaterial-embedded antenna exhibits a wide impedance bandwidth over the C band (from 3.77 GHz to 6.58 GHz). The results also indicate good radiation efficiency and antenna gain with a nearly omni-directional radiation pattern at the frequencies of interest.
