Based on energy transmission, in this paper, we designed 4*4 planar array patch antenna, the maximum gain of the proposed antenna structure is 20dBi at 5.8GHz. Based on the strong focusing ability of Bessel beam, we designed the annular metallic grating antenna and got Non-diffractive Bessel beam. We researched and compared the beam shape and focusing ability of the two antennas. The results demonstrate that the Bessel beam that is generated by the annular metallic grating antenna?has the characteristics of smaller main lobe size, higher strength, better directivity and longer transmission distance, so, it is more suitable for long distance energy transmission. |
