Abstract: In this paper, a design of dual-band Multiple Input Multiple Output (MIMO) antenna using a couple of novel Defected Ground Structure (DGS) is proposed. The antenna operates at 28GHz and 38GHz band for future fifth generation (5G) wireless technology. Combination of U and X shape on the ground, the suggested MIMO antenna has achieved not only multiband but also more compact size which is compared to theoretical microstrip antenna design. In addition, the MIMO antenna achieves low mutual coupling for all operating wide bands at close distance of 4.8mm thanks to proper position of DGS structure in antenna ground. The design of dual-band MIMO antenna is optimized and validated by using CST-MW Studio. |
