Embodiment Construction
[0027] The multi-beam antenna based on the one-dimensional microwave planar lens and the double tapered slot antenna array of the present invention is a multifunctional antenna synthesized by two independent structures. The one-dimensional microwave plane lens is a plane lens composed of four layers of separate artificial electromagnetic material surfaces. The phase-shifting units are printed on the surface of each layer, and these phase-shifting units are arranged in columns, that is, they are arranged continuously in the horizontal direction and arranged differently in the vertical direction according to different phase-shifting requirements. Nylon fixing columns are used between the surfaces of the four layers of artificial electromagnetic materials to maintain the air separation distance to achieve resonance. The double tapered slot antenna line array consists of 16 double tapered slot antenna units linearly arranged in the horizontal direction, and the double tapered slot...
