A novel compact triple‐band circularly polarized monopole antenna has been proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The antenna composes of a square patch etched with an X‐shaped slit and an improved ground plane. Furthermore, an inverted‐L slit is embedded in the square patch to improve axial ratio (AR) and impedance bandwidth. With a compact size of 44 × 46 × 1.5 mm 3 , the proposed antenna provides a relative wide 3‐dB AR bandwidth of 24.2% (2.22–2.83 GHz), 25.9% (2.92–3.79 GHz), and 9.3% (5.45–5.98 GHz), which successfully covering the bands of WLAN (2.4–2.484 GHz and 5.725‐5.850 GHz) and WiMAX (3.3–3.6 GHz).
