Abstract:
This paper presents the design of a compact rectangular dielectric resonator antenna (RDRA) for wireless applications. A metal plate has been attached to top surface of the RDRA to achieve significant reduction in the resonant frequency of the antenna. A simple microstrip feeding mechanism has been used to excite this compact rectangular DRA. Performance parameters such as resonant frequency, impedance bandwidth, and volume of this compact RDRA are compared with those of the conventional RDRA. Measured characteristics of these RDRAs are in good agreement with the simulated results. The size of the compact RDRA using a low dielectric constant (εr = 10.3) material resonant at 2.4 GHz is 30 mm × 10 mm × 6.3 mm with a ground plane size of 200 mm × 200 mm.
