Dielectric loaded Small Antenna Using Defected Ground Structure
Main Article Content
Abstract
A novel technique for designing small size printed antenna is proposed which is suitable for portable and multifunctional communication systems. The proposed design consists of material loading using high permittivity cylindrical rods underneath the patch and Defected Ground Structure (DGS) in the groundplane. The DGS consists of L-shaped, U-shaped and I-shaped slots. The size of the antenna has been reducedby66% as compared to a conventional antenna resonating at the same frequency. The other key featureof this antenna is impedance matched multiband response within 1-8GHzband with acceptable gain upto 4.1dB. All simulation results in this paper have been achieved from the CST Microwave Studio solver. Thissmall size antenna can be used in portable devices for WiMAX, GPS, WLAN and Bluetooth applications.
