摘要
提出了一种新型微带贴片天线,对不同角度下天线的反射损耗、带宽和方向图进行了仿真.与普通微带贴片天线相比,这种新型天线的相对阻抗带宽(S11衰减到-10dB)一般在20%以上,个别角度下能达到43%,而且方向图有较大变化.
This paper proposes a novel microstrip patch antenna. Then, the simulation of return loss,bandwidth and radiation patterns of different angles is presented. Compared with a normal microstrip patch antenna, this novel antenna. The opposite impedance bandwidth （ Sn decrease to - 10 dB） of this novel antenna is above 20% commonly. Some special angle antennas can achieve 43%. And the radiation patterns significantly changed.
