Abstract In this article, a wideband aperture coupled magneto‐electric (ME) dipole is proposed. The proposed dipole antenna is based on the traditional ME dipole which consists a pair of horizontal patches and a pair of vertical shorted patches. To achieve a wide impedance bandwidth, a stepped microstrip to slot transition is introduced in the antenna. Then, the vertical part of the dipole is tilted and two metal triangular prisms are employed to enhance the stability of the gain. A prototype antenna is fabricated and tested. Good agreements are found between the simulated and measured results. The measured impedance bandwidth for VSWR ≤2 is more than 125% (2.24‐10.0 GHz). The 1 dB gain bandwidth is about 108% (2.4‐8.0 GHz). Moreover, a stable unidirectional radiation patterns can be found across the 1 dB gain bandwidth.
