Abstract

An improved dual-band shorted planar monopole antenna with a bevel is presented for WLAN (wireless local area network). The parasitic element at the top of the antenna can reduce the height of antenna and can widen bandwidth. Compared with conventional planar monopole antenna, the antenna can work at dual band by adding rectangular-slots in vertical radiation elements. It can be concluded from the good results of return loss is less than -10dB within the frequency range of 2.15-2.53/5.05-5.49GHz, which could cover the WLAN dual-band of 2.4-2.484/5.15-5.35GHz. The acceptable agreement of measured and simulated results shows that this kind of antenna has perfect input impedance and pattern properties.
