摘要:This paper presents a wire type multiband strip antenna for WiMAX and WLAN operations by means of numerical simulations. The dimension of the antenna is 39×30 mm2 and provides an impedance bandwidth of 300 MHz (2350-2650 MHz) and 130 MHz (5490-5620 MHz) at lower and upper frequency band respectively, which fully covers the 2.4, 2.5 and partially covers the 2.3, 5.5 GHz bands. The antenna contains very high peak gains of 8.25, 8.43, 8.46 and 6.43 dBi at 2.3, 2.4, 2.5 and 5.5 GHz band respectively with less than 0.2, 0.1, 0.3 and 1.5 dBi gain variations within the 10 dB return loss bandwidth. The VSWR of the antenna varies between 1.20~1.80 and 1.06~1.83 at the lower and upper resonant frequency bands respectively and the peak values of the return loss are -20.85 and -30.71dB. The antenna has good omnidirectional radiation characteristics at E-plane and H-plane.
