Abstract

In this paper, a conical horn antenna is introduced in the X-band and in the presence of a metamaterial lens. The metamaterial lens is located at the aperture of ashort horn antenna that the length of the horn is half the one of the corresponding optimum versions. The phase velocity in the metamaterial lens is more than the phase velocity in an environment without lens, so the phase distribution in the aperture of antenna is uniform and the gain of the short horn antenna increases. Metamaterial cells are designed in the form of printed circuit board that have easy to build and suitable cost.The geometrical characteristics of metamaterial lens is calculated by designed formulas and finally ;particls swarm optimazition algoritm  is used to achieve proper gain and radiation characteristics in the desired frequency band .The radiation characteristics of an antenna with a metamaterial lens are similar to that of an antenna with optimum length in the desired frequency band; the difference is that the weight and volume of these antennas are reduced, so they have better performance in satellite systems and radars.
