This article presents a millimeter‐wave (mmWave) microstrip patch antenna (MPA) with a vertically coupled split ring metaplate (VCSRM). The narrow bandwidth and low gain of MPA are improved using VCSRM by periodically arranging split rings on the front and backsides of a dielectric slab. Numerical and experimental results show that the proposed antenna attains good radiation pattern, a high gain of 11.94 dBi, and a measured fractional bandwidth covering 26.58 to 29.31 GHz (9.77%). The gain of the antenna is increased by 5.35 dBi and the bandwidth is improved by 3.87% when compared to MPA without VCSRM. Thus, the proposed antenna with a small size of 18 × 22 mm 2 is suitable for mmWave applications.
