| Abstract: |
| Antenna array can generate different farfield radiation patterns by u
sing switch to turn on or turn off the excitation of the array elements. In this
way, a broad or narrow beam can be realized for an antenna array. The des
ign of a 24-element linear antenna array is presented. Then an improved genetic
algorithm(GA) and its weight objective function model are proposed
to optimize the amplitudes of the currents of the array elements. Calculated re
sults show that the radiation patterns of the broad beam and the narrow beam mee
t the design requirement. Finally, the software HFSS is used to simulate. The ca
lculated results are in good agreement with the simulated ones, which proves
the validity of the proposed method. |
