Graphene conductive ink based microstrip line fed circular patch is presented in this paper. The main objective of this work is to replace copper with graphene which is an emerging promising material, in the field of patch antennas with conventional rigid substrates using a simple printing technique and to measure its performance. The prototyped screen printed graphene antenna is perfectly radiating and the return loss, VSWR and gain of the graphene antenna is found to be better than conventional copper antenna. Also, the bandwidth of the graphene antenna is 1.6 times greater than that of the conventional copper antenna on rigid substrate.

一种新颖的基于石墨烯导电墨水的圆形贴片天线，用于2.4 GHz应用

本文介绍了基于石墨烯导电油墨的微带线馈电圆形贴片。这项工作的主要目的是使用简单的印刷技术，在具有常规刚性基板的贴片天线领域中，用石墨烯代替铜，石墨烯是一种新兴的有前途的材料，并测量其性能。原型丝网印刷石墨烯天线具有完美的辐射性能，石墨烯天线的回波损耗，VSWR和增益均优于传统的铜质天线。同样，石墨烯天线的带宽是刚性基板上常规铜天线的带宽的1.6倍。
