In this article, a novel wireless local area network (WLAN) frequency range monopole antenna is designed and manufactured for multi‐input multi‐output (MIMO) applications. The proposed antenna consists of two L‐shaped slots in the S‐shaped radiating patch. In this structure, the S‐shaped monopole antenna can create dual resonances within the WLAN range. Placement of two L‐shaped slots within the S‐shaped monopole antenna creates an extra resonance; the desired resonant frequencies are obtained by adjusting the dimension of the S‐shaped and the L‐shaped structures. The operating frequencies of the proposed antenna are 2.4/5.2/5.8 GHz, which covers WLAN system. Various configurations of array of this S‐shaped monopole antenna for MIMO application are also studied. Prototypes of the proposed antenna have been constructed and studied experimentally. Good return loss and radiation pattern characteristics are obtained in the frequency band of interest. Simulated and measured results are presented to validate the usefulness of this small proposed antenna structure for MIMO applications. © 2013 Wiley Periodicals, Inc.
