Using Lens at Aperture of Antenna for NFF and FFS

Abstract

Antenna technology is developing in today’s world where data transmission is main. In such environment number of different antennas is developed for near field and far field focusing. In this paper a linear feed antenna array is presented which is a sectoral horn H-plane antenna having dielectric lens of biconvex shape are placed in the aperture. Only in h-plane our antenna focuses its beam for providing high aperture and small width of linear array illumination. For the array length illumination in the other plane the field distribution is found on the array having nice agreement of 10 GHz frequency prototype. In this paper we use CST tool for simulation.
