Firstly, several new resonant points are introduced based on the traditional H-shape slot to improve the bandwidth. The higher-order resonant modes in the sub-cavity are excited by the ground-based coplanar waveguide feeding network. A wide impedance bandwidth can be achieved by introducing the higher order modes closer. By this means, the final bandwidth of the slot antenna can reach 20.7% (12.1–14.9 GHz). Secondly, the antenna is further improved by loading the miniaturized metasurface to solve the gain degradation in the high-frequency part. The metasurface is composed of four sequentially rotated 3×3 meta units and a metal via is etched on each unit to achieve miniaturization. The gain in the high operating band is increased with a 1.7 dBi average and 2.3 dBi maximum while the size of the metasurface is reduced. The results demonstrate that the proposed antenna achieves an impedance bandwidth of 27.6% in the range from 11.25 to 14.85 GHz with a peak gain of 9.4 dBi at 14.1 GHz.
