Small and compact rectangular dielectric resonator antenna for WLAN applications

In this paper, small dielectric resonator antenna was design and developed by using high permittivity dielectric material of 55. The dimensions of the dielectric resonator were 5.4 mm (width), 9.3 mm (length), and 3.14 mm (height). This DRA operate at a frequency around 5 GHz. It was excited with microstrip line where the position of the DR on the microstrip was varied to get good coupling. CST Microwave Studio was used for the simulation of the return loss and radiation pattern. A comparison between the measured and simulated value of the return loss and radiation pattern were also discussed.
