Abstract
In this paper, a 2×2 multi-layer array antenna based on the metamaterial concept is proposed at 28 GHz for 5-Generation (5G) applications. The feed network is designed in the first layer. This network feeds the rectangular patch located in the first layer using four shorted-pins (SPs). To realize the metamaterial environment, a novel unit-cell was designed. In the first layer between the two dielectrics, 2 unit-cell rows are used. In the second layer and adjacent to the patches, 4 rows of metamaterial unit-cells are loaded. Each of the metamaterial rows contains 6 unit-cells. As such, the antenna gain has increased more than 10 dB from the prototype without any metamaterial structures. The final dimensions of the proposed array antenna are 30×35.2×0.508 mm3. To prove the design, the proposed antenna was fabricated. The simulated and measured maximum gain at 28 GHz are 18.28 and 17.91 dB, respectively.
