This paper presents the performance improvement of a microstrip patch antenna (MPA) using a novel double‐layer concentric rings metaplate (DLCRM) for fifth‐generation (5G) millimeter wave (mmWave) applications. To improve the performance of the proposed antenna, a DLCRM is placed above the MPA having an air gap. The design procedure is explained using the different shapes of DLCRM, and the double negative (DNG) characteristic of metamaterial is verified. Moreover, the effects of the DLCRM on the MPA are validated by experimental results. The proposed antenna attains a high‐gain of 11.59 dBi and has an impedance bandwidth from 27.1 GHz to 29.56 GHz (8.68%) which is the potential 5G mmWave band. The measurement result shows that the bandwidth of the antenna is improved by 2.04%, and broadside gain is increased by 4.69 dBi compared to the MPA without a DLCRM. Thus, the antenna provides high gains with wide bandwidth that makes it a suitable candidate for 5G mmWave applications.
