Abstract :
This paper presents a coplanar waveguide (CPW) fed hybrid monopole/dielectric resonator antenna for W-band imaging system applications. The proposed antenna consists of a CPW-fed printed monopole and cylindrical dielectric resonator. In this hybrid configuration, the printed monopole is used as an effective radiator as well as to excite the dielectric resonator. The obtained simulation results show that the 10 dB return-loss impedance bandwidth of the proposed antenna can reach up to 16% with the center frequency at 101.85 GHz (93.7 GHz-110 GHz). Also, the proposed antenna shows nearly omni directional radiation characteristics with maximum achieved realized gain of about 2.67 dBi at 94 GHz. The prototype fabrication procedure is outlined.
