A novel planar monopole antenna with a compact radiator is proposed for tri‐band operation. The antenna consists of double C‐shaped monopole strips and an inverted U‐shaped shorted strip to generate three resonant modes. The radiator of the antenna occupies a small size of 9 × 14.8 mm 2 . By optimizing the designed parameters of the radiator, good impedance matching can be obtained over the three desired bands. The prototype of the designed antenna is fabricated and tested. Measured results show that the antenna has 10‐dB return loss impedance bandwidths of 340 MHz (2.39–2.73 GHz), 560 MHz (3.23–3.79 GHz), and 910 MHz (5.05–5.96 GHz), which can cover both 2.4/5.2/5.8 GHz wireless local area network and 2.5/3.5/5.5 GHz worldwide interoperability for microwave access operating bands. The features of compact size, simple structure, and good tri‐band performance make the antenna a promising candidate for practical wireless applications. © 2015 Wiley Periodicals, Inc.
