Abstract :
This paper presents an enhanced Offset Fresnel zone plate antenna (FZPA) using dielectric rods. The dielectric rods enhance the antenna side lobe level and cross polarization level. The proposed antenna is simulated using XFDTD software and fabricated which is verified by good agreement between simulated and measured results. Variation effects of the focal-length-to diameter (f/D) ratios are investigated. Also effect of different offset angle on antenna performance is discussed.
