Design and development of a wideband tree shaped fractal dielectric resonator antenna
Design of a wideband tree shaped fractal dielectric resonator antenna (DRA) is proposed in this paper. Trapezoidal shaped conformal strip feed is used as feeding mechanism. Implementation of fractal geometry on DRA has been utilized to reduce Q-factor and subsequently achieve wide bandwidth (BW). Tetrahedron shaped notches are created as fractal iterations to improve bandwidth. Impedance bandwidth of about 86.32%, with frequency range from 4 to 10.1 GHz is achieved. Average gain of about 6 dBi over the entire band of interest is achieved. Various design parameters, and corresponding results are discussed.
