In this article, compact monopole antenna with independent resonant frequency tuning capability is proposed.The antenna radiating patch consists of a simple, bent monopole element and an open stub. The bent monopole acts as a main radiator in 2.5 GHz band, whereas the open stub serves in 5.5 GHz band. A prototype of the proposed antenna was fabricated, and the reflection and radiation characteristics were measured to validate the antenna performances. Measured impedance bandwidths (VSWR < 2) exhibits dual-broadband resonances, which are 2.08–3.02 GHz (lower band) and 5.13–6.15 GHz (upper band), corresponding to 36.9 and 18.1%, respectively. Therefore, VSWR bandwidth of the proposed design covers not only the WiBro, WiMAX, Bluetooth, 2.4 GHz WLAN, S-DMB, but also the 5.2/5.8 GHz WLAN services. The peak gain was 5.76 dBi. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:2548–2552, 2012; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.27159
