Submillimeter wave 8×1 antenna array With dielectric rods to improve the radiation pattern

In this work, a submillimeter wave 8×1 element antenna array is presented. The array has been designed to be used in the 250-320 GHz band for imaging applications. The system provides a uniform behavior in the whole frequency range of interest, keeping the sidelobe level below -10 dB in the array pl...

Summary:In this work, a submillimeter wave 8×1 element antenna array is presented. The array has been designed to be used in the 250-320 GHz band for imaging applications. The system provides a uniform behavior in the whole frequency range of interest, keeping the sidelobe level below -10 dB in the array plane. To improve the directivity and the return loss, a set of dielectric rods has been utilized. Experimental results showing the full array behavior are also presented.
