A high-gain and broadband dielectric resonator antenna array with substrate-integrated-waveguide feed network for 67GHz
We have proposed and investigated a high-gain and broadband dielectric resonator antenna (DRA) array with simplified substrate-integrated-waveguide (SIW) feed network for 67GHz band in this paper. A double-layered SIW feeding network with wideband H-junction and wideband high-gain slot dielectric resonator antenna array is employed to achieve high gain and wideband performance simultaneously. The simulated impedance bandwidth of 15% and a gain up to 13.9 dB have been offered. Together with the advantages of low-profile and low fabrication costs, the proposed antenna array could serve as a promising candidate for millimeter-wave wireless communication systems.
