This article is aimed to discuss a novel high directional flared quasi‐Yagi offset feed monopole UWB antenna. The proposed antenna is stamped on an FR‐4 dielectric material of dimensions 40 mm × 48 mm × 1.6 mm, which is exhibiting a permittivity of 4.4 and a loss tangent of 0.019. It operates within a frequency spectrum of 3.06 to 12.37 GHz that includes the complete FCC ultra‐wideband of 3.1 to 10.6 GHz. Maximum peak gain and radiation efficiency of this antenna are found to be 10.07 dBi at 10.4 GHz and 92.64% at 4.7 GHz, respectively. The presented antenna employs a novel structure comprising of flared elements, directors and offset feed to a planar monopole for achieving directional behaviour. Thanks to the novel technique for enhancing uni‐directional characteristics in the entire operating band. Prototype of the proposed structure is fabricated and measurement results are verified with the simulation results. A good matching is also found between them.

一种新颖的偏置馈电喇叭形单极准八木高定向超宽带天线

本文旨在讨论一种新颖的高方向喇叭形准八木偏移馈电单极UWB天线。拟议中的天线印在尺寸为40 mm×48 mm×1.6 mm的FR-4介电材料上，介电常数为4.4，损耗角正切为0.019。它在3.06至12.37 GHz的频谱内运行，其中包括3.1至10.6 GHz的完整FCC超宽带。该天线的最大峰值增益和辐射效率分别在10.4 GHz和4.7 GHz下分别为10.07 dBi和92.64％。提出的天线采用了一种新颖的结构，该结构包括喇叭形元件，指向矢和向平面单极子的偏置馈电，以实现定向性能。由于采用了新颖的技术，可以在整个工作频段内增强单向特性。制造了拟议结构的原型，并通过仿真结果验证了测量结果。他们之间也找到了很好的匹配。
