摘要

提出了一种具有超宽带性能的紧凑型明信片形天线的设计方案。该天线的顶部由一个改进的矩形贴片组成，而底部则设计了一个优化的带阶梯槽的局部接地面，这有助于改善期望频率范围内的阻抗匹配。天线的整体尺寸为20 × 20 mm2。从2.75 GHz到30 GHz以上，阻抗带宽为27.25 GHz。此外，该天线的分数带宽为166.4%，比带宽为10.9:1，带宽尺寸比(BDR)为5136。此外，在工作频率范围内，观测到的天线峰值增益为~ 5.56 dBi，平均增益为~ 3.4 dBi。

Postcard Shaped Super Wideband Antenna with High BDR

The design of a compact postcard-shaped antenna is presented for super wideband performance. The top side of the proposed antenna comprised of a modified rectangular patch, while an optimized partial ground plane with stair-shaped slots is designed on the bottom side, which helps to improve the impedance matching in the desired frequency range. The overall size of the antenna is 20 × 20 mm2. An impedance bandwidth of 27.25 GHz is observed starting from 2.75 GHz up to more than 30 GHz. Furthermore, the proposed antenna offers a fractional bandwidth of 166.4 %, a ratio bandwidth of 10.9: 1, and a bandwidth dimension ratio (BDR) of 5136. In addition, the observed peak gain of the proposed antenna is ∼ 5.56 dBi with an average gain of ∼ 3.4 dBi for the operating frequency range.
