In this paper, a novel design of the probe-fed dual-wideband cylindrical dielectric resonator antenna is investigated. The antenna operates in 2.4 GHz and 12 GHz bands with a frequency ratio of about 1:5. The antenna consists of two dielectric resonators (DRs). The one in the lower band is a dielectric resonator antenna (DRA), and the other is a Fabry-Perot resonator (FPR) antenna (FPRA) in the upper band. The antenna is excited by vertical strips and probes to DRs at 2.4 GHz and 12 GHz, respectively. The proposed dual- wideband antenna has -10dB bandwidths of 9.51-13.61 GHz (34.2%) and 2.21-2.63 GHz (17.5%), with maximum gains of 10.66 dBi (at 12.54 GHz) and 4.32 dBi (at 2.60 GHz), respectively. This antenna has the advantage of bandwidth.
