Research and Analysis about Array Antennas in Mobile Communications

Abstract:

Because the direction of a single antenna is limited, and for strengthening the direct radiant ability of the antenna, we will put the weaker direction antennas together in some way to constitute an antenna array system. The antenna array is also called the array antenna or a disperse antenna array. The antenna cell can be the symmetry center-fed dipole, the aperture antenna, the circle antenna or other forms of the antennas whose direction are limited. In practice, the antenna array is almost constituted of similar antenna cells. I have mainly completed the antenna array direction diagram in conditions of some kinds of parameters. And at last, I get the useful results for practice. This also provides theories basis for the analysis of smart antenna.
