Abstract

This paper presents a wing-shaped ultra-wide band monopole antenna and its dual band-notch operations. Over a partial ground plane, the proposed antenna is designed with a wing-shaped radiating patch by connecting four circular conductors at both top-sides of the feedline. The antenna operates within 3.1∼15.36 GHz with a fractional bandwidth (−10 dB) of 132.83% by covering a small area of $25\times 35$ mm2 on a Rogers RT5880 substrate. Impedance matching of the antenna is stable due to its −17 dB bandwidth of 8.55 GHz and 58 dB minimum return loss. Peak gain of the antenna is 5.09 dBi while an average gain of 3.61 dBi is maintained over the entire −10 dB bandwidth of 12.26 GHz. Simulated average radiation efficiency is 99% and total efficiency is 94% in the proposed antenna. For band-notches, two slot-lines are applied on the upper part of the radiating patch where the first slot eliminates the 5G band at 3.5 GHz and the second slot eliminates the WLAN band at 5.8 GHz frequencies from the antenna bandwidth without hampering the overall performance. The proposed antenna is expected to be useful for ultra-wide band integrated communication systems.

用于双带陷波操作的翼形超宽带天线

介绍了一种翼形超宽带单极天线及其双带陷波工作原理。在部分地平面上，该天线通过在馈线的两端连接四个圆形导体，设计了一个翼形辐射贴片。该天线在罗杰斯RT5880衬底上覆盖25 × 35 mm2的小面积，工作在3.1 ~ 15.36 GHz范围内，分数带宽(- 10 dB)为132.83%。8.55 GHz带宽为- 17 dB，最小回波损耗为58 dB，阻抗匹配稳定。在12.26 GHz整个−10 dB带宽范围内，天线的峰值增益为5.09 dBi，平均增益为3.61 dBi。该天线的模拟平均辐射效率为99%，总效率为94%。对于带缺口，在辐射贴片的上部应用两条槽线，其中第一个槽从天线带宽中消除3.5 GHz的5G频段，第二个槽从天线带宽中消除5.8 GHz频率的WLAN频段，而不影响整体性能。该天线有望用于超宽带综合通信系统。
