A Hybrid Graphene-Metal IFA Antenna with Dynamically Tunable Operating Frequency at Microwave Freauencies

Abstract

This paper presents a hybrid graphene-metal IFA antenna with dynamically tunable operating frequency. A small piece of single-layer graphene is used to connect with metal structure. This paper shows that the operating frequency of the antenna with special structure can be dynamically tuned by changing the surface resistance of single-layer graphene. The operating frequency of the antenna can be changed from Ll band of Global Positioning System to B3 band of BeiDou Navigation Satellite System.
