Multi-Band Rectangular Dielectric Resonator Antenna for Wireless communications

In this paper, a Multi-band rectangular dielectric resonator antenna is presented. The fed method consists on a probe which is inserted through the dielectric resonator. The dielectric resonator has a small size (20 mm × 20 mm × 7 mm). The simulated bandwidths are 8.51 – 8.72 GHz, 9.90 – 11.58 GHz, and 13.01 – 13.11 GHz. The total fractional obtained bandwidth is 18.79%.
