In this article, both the patch and the ground plane of the conventional rectangular patch antenna are sliced into 5 strips along its E‐plane, respectively. The strip widths of the sliced patch are the same, and the gaps between the neighboring strips are uniform. Considering the solder and the current distribution on the ground, the inner 3 strips of the sliced ground are kept the same widths and just change the widths of the outer strips and the gaps, and these gaps are the same as well in the designs. Then, the conventional and one‐sliced antenna prototypes are fabricated to be compared. They are excited by the coaxial probes and the substrates are Wangling F4BM220, where the height is 1.50 mm, the permittivity is 2.20, and its tangent loss is 0.001. The dimension of the substrate is 40 × 40 mm. The measured results agree well with those of the simulations. Both the impedance and realized gain bandwidths of the sliced antenna are wider than those of the conventional ones. However, the realized gain reduces after being sliced. Finally, the parametric study on different gaps of the ground plane is also investigated.
