Abstract :
A novel compact triple-band monopole microstrip antenna for WLAN applications is proposed. The proposed antenna is made up of two one-quarter wavelength resonating components, fed by a 50 ohmic microstrip line. The configuration is simple. The resonating frequencies of the proposed antenna are 2.5 GHz and 4.8 GHz, respectively, the bandwidth is about 500 MHz (2.25~2.75 GHz) and 2.63 GHz (3.82~6.45 GHz) (return loss less than -10 dB), covering the triple bands of WLAN system. The lower and higher resonant frequencies can be easily tuned by adjusting a few parameters of the presented antenna. This antenna satisfies the requirements of wireless local area network(WLAN) 802.11(2.4~2.484 GHz, 5.15~5.35 GHz, 5.725~5.825 GHz) applications. The softwares of Ansoft HFSS11 and CST Microwave Studio are used to simulate and optimize the antenna.
