This paper presents a compact dual-band circularly polarized cylindrical dielectric resonator antenna (CDRA) that operates at 38/60 GHz. The proposed design is contained a single wafer of silicon and two annular slots to excite the DRA. Shorted outer and inner annular slots generate circular polarization in both bands. The proposed design of CDRA achieves a 3-dB AR bandwidth of 3.34/7.53%, with an impedance bandwidth of 9.74/24.01% at 38/60 GHz. Also, it has excellent radiation characteristics, which its radiation efficiency and peak gain 7.6 dBi and 95.22%, respectively. The proposed CDRA with dual-band resonances and gain bandwidth has the excellent potential to be applied for mmwave wireless communications at the 38/60 GHz bands.
