This article reported patch antenna functioning at Wi- Fi and 5G bands. Wi-Fi band (2.4 GHz) is obtained by loading Epsilon Negative Transmission Line (ENGTL) metamaterials into the patch radiating at 5G band (3.5 GHz). To acquire Circular Polarization (CP) at 5G band, conventional square patch is embedded with poly fractals. The experimental and simulated data are in close proximity. The obtained impedance bandwidth is 4.01% at Wi-Fi and is 10.68% at 5G band. CP bandwidth is 2.43% at 5G. This mix of ENGTL as well as fractals provides good compactness appropriate for portable gadgets

基于ENGTL的Wi-Fi和5G天线

本文报道了贴片天线在Wi-Fi和5G频段上的功能。通过将Epsilon负传输线（ENGTL）超材料加载到以5G频段（3.5 GHz）辐射的贴片中，可以获得Wi-Fi频段（2.4 GHz）。为了在5G频段获得圆极化（CP），常规的方形贴片嵌入了多形分形。实验和模拟数据非常接近。在Wi-Fi处获得的阻抗带宽为4.01％，在5G频段处为10.68％。5G时CP带宽为2.43％。ENGTL和分形的混合提供了适合便携式小工具的良好紧凑性
