摘要

The discovery of Graphene has created new applications for the next generation electronics due to its electrical characteristic. A compact patch antenna with graphene as conducting media has been designed for wearable, medical and consumer electronics application at 24 GHz. The patch has a dimension of 5x5 mm and is designed over 0.254 mm thick roger material. The antenna has been combined to make it an array form for increasing its gain while various antenna parameters have been obtained for its comparison with copper conductive patch. The ground patch is made of Perfect Electric Conductor (PEC) in both cases. Various parametric results show that graphene patch similar to copper patch provides a comparable return loss and VSWR although there has been observed some decrease in its gain and efficiency and an increase in its bandwidth Thus, graphene can be a good alternative to copper conductive patch within higher GHz and THz frequency range.
