In this article, a compact patch antenna using split‐ring resonators (SRRs) is proposed.To reduce the size of a conventional patch antenna, the SRRs are inserted between the main patch and ground. The size reduction is achieved by utilizing the high equivalent permeability characteristics of the proposed structure. The resonance frequency of the antenna shifts from 6.6 to 4.67 GHz without changing the fractional bandwidth and the gain characteristic. A size reduction of 29.3% is achieved, and a maximum gain of 4.84 dBi is obtained. © 2011 Wiley Periodicals, Inc.
