✦ Synopsis

A triple-band dipole antenna with wideband balun integration is proposed in this article. This antenna consists of two dipoles, a wideband balun and feeding line. These three parts are integrated into a compact design, which has a small size of 30 Â 25 Â 0.8 mm 3 based on the substrate having a dielectric constant of 2.55. The simulated results show that triple bands of 2.40-2.59 GHz, 3.42-3.80 GHz, and 5.06-5.95 GHz are attained by this antenna, and can cover the bands of WLAN/WiMAX. The simulated and measured radiation patterns at different center frequency are also demonstrated and the designs of dipoles and balun are also provided, which exemplify omnidirectional characteristics in the H-plane.
