Dual band dielectric resonator antenna operates at 2.4 GHz and 5.4GHz

Abstract

This thesis explains about the design of dual band antenna by using a dielectric material. The antenna is made from a dielectric resonator antenna (DRA) with a permittivity, r ? , is 10. Rectangular DRA is used to ease the fabrication process. The operating frequency chosen to be design is 2.4 GHz and 5.4 GHz. Notched DRA technique is used for dual band application purpose. In order to drive the antenna to function, it is placed on top of the ground plane. FR4 board is chosen as a ground plane for this research with a dielectric constant is 4.6. Alphabet “I” is used in this study for the aperture coupling at the substrate. Meanwhile, for the feeding line, microstrip line is used to match with 50? network. The simulation is run by using Computer Simulation Technology (CST) software. This software provides 3D design of the antenna and easier visualizes the antenna properly. The result is then compared to the actual result obtained by measurement. The fabricated product is attached to a network analyzer via SMA connector. S11 output obtained during simulation and measurement will be discussed thoroughly.
