摘要：

A double-layer metamaterial with epsilon-near-zero (ENZ) properties is proposed loading on the patch antenna. The double-layer metamaterial that has two layers of the same material and structure is produced on FR4 substrate. The gain and radiation directivity of the patch antenna can be greatly improved covering with the proposed ENZ metamaterial. Simulation results show that by coating the ENZ superstrate, the gain of the patch antenna is increased from 5.99 dBi to 10 dBi, corresponding to 66.9% gain enhancement and greatly improved radiation directivity. While the performance of the patch antenna is improved, the working frequency and bandwidth of the patch antenna are not affected. © 2023 by Begell House, Inc.
