摘要

本文着重介绍了天线设计领域中超材料的出现。在增益、指向性、主瓣和副瓣电平、带宽等参数方面提高天线的性能;超材料与天线一起用作均匀的平面透镜。设计了一种新型的“U”形开槽贴片天线及其2×2阵列，用于2.4 GHz频段，并利用CST软件进行了仿真。给出了使用和不使用超材料时这些天线的性能评估。将超材料透镜嵌入阵列后，增益提高了18.57%，指向性提高了25.31%。它还减少了1dB的回波损耗，提高了4.69%的带宽。

Performance Analysis of Uniform Meta-material Lens Embedded U-shape Slotted Patch Antennas

This paper emphasizes on the emergence of Metamaterials in the field of antenna designing. For enhancing the performance of the antenna in terms of various parameters viz. gain, directivity, main lobe and side lobe levels, bandwidth; metamaterials are used as an uniform flat lens along with the antenna. A novel 'U' shape slotted patch antenna & its array of 2×2 is designed for 2.4 GHz frequency band and simulated using CST software. The performance evaluation of these antennas with and without the meta-material is illustrated. Embedding the meta-material lens with array results in improvement of the gain (18.57%), directivity (25.31%). It also reduces the return losses by 1dB and enhances the bandwidth by 4.69%.
