Abstract:


Background: A wide-band wide-beam Dielectric Resonator Antenna (DRA) is proposed in this paper.

Methods: A cylindrical dielectric resonator operating in TM01δ mode is placed on a hybrid-structure ground which consists of a corner-reflector and a pentagon plate with edge-fold. With this structure, wide-band wide-beam characteristics can be achieved.

Results: From simulation results, the impedance bandwidth (|S11|< -10 dB) of the antenna is from 1.8 to 3.14 GHz. The radiation pattern is stable, and the 3dB beam-width of H-plane is larger than 160° over the impedance bandwidth.

Conclusion: A prototype of the proposed antenna is fabricated and tested, and the testing results are in agreement with the simulation.

Keywords:
