Nine Shaped Dual Wideband Rectangular Dielectric Resonator Antenna

Abstract

An objective of this paper is to design a dual wideband Rectangular Dielectric Resonator Antenna (RDRA) using a novel Nine-shape with simple feeding technique. This newly shaped antenna is fed by triple stub micro-strip feedline. This type of feeding results in good coupling and wide bandwidth. Our proposed Nine-shaped DRA works at "C" band, "X" band and "Ku" band frequencies and provides dual bands with broad bandwidth nearer to 45.59%, and 28.1% respectively. The Nine-shaped structure and the triple stub microstrip feeding provides a dual wide band operation.
