A low‐profile wideband patch antenna utilizing double‐tuned impedance matching technology is investigated in this paper. To extend the operation bandwidth of the antenna, the step‐folded probe is used here to realize the double‐tuned impedance matching. Using equivalent circuit theory, the working principle of the antenna is analyzed and discussed. The full‐wave simulation is carried out to optimize the design while the prototype of the antenna is fabricated and measured. Good agreement between the simulation and measurement can be observed. The measured results show that the antenna has a height of 0.12 λ L ( λ L is the free space wavelength corresponding to lowest frequency) and the −10 dB impedance bandwidth can cover 1.60‐2.83 GHz (55.5%). The low profile and wide operation bandwidth of the antenna make it a good candidate for wideband wireless communication systems.
