Broadband dual‐frequency spider‐shaped printed dipole antenna for WLAN applications

A novel broadband dual-frequency spider-shaped dipole antenna for 2.4/5.2 GHz wireless local area networks (WLAN) is proposed. The antenna consists of a double-sided printed dipole, whose long arms and short center-stubs can produce dual bands and lead to good impedance matching in a wide dual-band without external matching circuitry. For the experimental study, excellent performance for operating frequencies across 2240–3260 MHz and 4700–5970 MHz bands has been observed. Good radiation characteristics of dipole-like patterns, and 2.6- and 4.6-dBi peak antenna gains for the lower and upper bands, respectively, have been obtained. And this antenna could be easily printed and integrated on the system circuit board for WLAN applications. © 2010 Wiley Periodicals, Inc.
