Abstract EN
A wideband antenna is designed based on Q factor in this paper.
Firstly, the volume-surface integral equations (VSIEs) and self-adaptive differential evolution algorithm (DEA) are introduced as the basic theories to optimize antennas.
Secondly, we study the computation of Q of arbitrary shaped structures, aiming at designing an antenna with maximum bandwidth by minimizing the Q of the antenna.
This method is much more efficient for only Q values at specific frequency points that are computed, which avoids optimizing bandwidth directly.
Thirdly, an integrated method combining the above method with VSIEs and self-adaptive DEA is employed to optimize the wideband antenna, extending its bandwidth from 11.5~16.5 GHz to 7~20 GHz.
Lastly, the optimized antenna is fabricated and measured.
The measured results are consistent with the simulated results, demonstrating the feasibility and effectiveness of the proposed method.
