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.
