【摘要】 本文提出了一种可应用于无线局域网的双U型槽加载三频带微带贴片天线。通过在辐射贴片的适当位置开两个U型槽,使天线能够工作在WLAN的3个频带,包括2.45GHz、3.6GHz和5.2GHz。在这3个频段内,天线的阻抗带宽分别为9%、9.7%和7.8%;增益分别达到了0.9dB、6.9dB和6.7dB。本文给出了相应的设计原理和参数分析,为微带天线的进一步研究奠定了基础。更多还原

【Abstract】 In this paper, a tri-band microstrip patch antenna with double U-slot which can be used in the wireless network（WLAN） system is proposed.The antenna can work through three band of WLAN including 2.45 GHz、3.6 GHz and 5.2 GHz,by adding dual U-slot in the proper place of the radiation patch.The impedance bandwidth(S₁₁<-10 dB)of 9%、9.7% and 7.8% are achieved at central frequencies 2.45 GHz、3.6 GHz and 5.2 GHz;the gain is more than 0.9 dB 、6.9 dB and 6.7 dB.The corresponding design principle and simulation results are given in this paper which can lay a foundation for the future research of microstrip patch antenna.更多还原
