Abstract

A frequency-tunable tri-band metamaterial-inspired antenna is proposed. The antenna consists of patches, interdigital capacitors, and meander lines inductors, and loaded with a split ring resonator. The metamaterial-inspired antenna can provide three band operations at 1.575/2.1/2.6 GHz, which cover the GPS band1, LTE band1, and LTE band7 applications. The antenna has three different current flows, which create different resonances. The proposed antenna can adjust each resonant frequency independently by adjusting the antenna parameters, the length of SRR, meander lines, and ground branch line, which can affect each current path. The prototype antenna has been designed and fabricated using the FR4 substrate with a thickness of 1.6 mm and a dielectric constant of 4.3. The measured return loss and far-field radiation patterns of the fabricated antenna have good agreement with the simulated results. The fabricated antenna shows well-matched impedance characteristics with a reasonable bandwidth and has an omnidirectional radiation pattern at each operating band. The proposed antenna has the advantages of multi-band, frequency-tunable characteristics, and easy fabrication, and can be widely used in various wireless mobile communication systems.

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
