In this letter, a compact multiband microstrip‐fed planar monopole antenna is presented. The proposed antenna has three resonance modes which cover three bands of wireless standards including universal mobile telecommunications system band (1920–2170 MHz), 3.5 GHz worldwide interoperability for microwave access band (3.4–3.6 GHz), and 5.2 GHz wireless local area network band (5.15–5.35 GHz). The antenna has a simple structure which consists of a rectangular radiation patch with two symmetric folded slots for size reduction, a step‐shaped microstrip feed line, and a rectangular ground plane. Owing to fully printed, simple and small configuration, the proposed antenna fabrication is cost effective. The designed antenna has a total dimensions of 30 × 34×0.8 mm 3 which makes this antenna a good candidate for mobile communication applications. The radiation characteristics such as gain, radiation patterns and radiation efficiency of the suggested antenna are investigated. The antenna radiates Omni‐directionally in H‐plane and bidirectionally in the E‐plane. In this design, very high radiation efficiency over the operating bands is obtained. According to the mentioned advantages, the proposed antenna can be a good choice for multiband wireless applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:844–847, 2016
