The design and analysis of a compact dual-wideband multi-mode resonant printed quasi-Yagi antenna with dual-driven element is presented. In the design, an orthogonal dual-bowtie dipole is applied as the driven element to achieve the dual-band characteristic with minimal size. The dual-bowtie dipole is designed to operate in the multi-mode resonance to expand its bandwidth. The structure is 60% smaller than the wideband printed Yagi antennas in the literature. Besides, the designed antenna achieves two wide fractional bandwidths of 44% (0.84–1.31 GHz) and 115% (1.56–5.78 GHz) with a stable high gain of 3.4 ± 0.8 and 3.6 ± 1.6 dBi, respectively. Simulation and measurement results are included.

具有双驱动元件的紧凑型双宽带多模印刷准八木天线

提出了一种具有双驱动元件的紧凑型双宽带多模谐振印刷准八木天线的设计与分析。在设计中，正交双领结偶极子用作驱动元件，以最小的尺寸实现双频特性。双领结偶极子设计用于在多模谐振下工作以扩展其带宽。该结构比文献中的宽带印刷八木天线小60％。此外，设计的天线可实现两个较宽的分数带宽，分别为44％（0.84-1.31 GHz）和115％（1.56-5.78 GHz），并具有3.4±0.8和3.6±1.6 dBi的稳定高增益。包括仿真和测量结果。
