摘　　要：提出了一种小型化宽频带双频天线的设计。该天线由一个E形微带贴片和一个偶极子天线组合而成,产生高低2个频率,且低频段带宽可控。仿真的-10dB阻抗带宽分别为83MHz(2.4～2.485GHz)和812MHz(5.1～5.912GHz)。能够覆盖IEEE802.11b/g(2.4～2.483GHz)和IEEE802.11a(5.15～5.825GHz)工作频段,并对仿真结果进行了分析。同时给出的设计双频段宽带小型化天线的方法,可以对高低2个频段分开设计,对工程实践有一定的指导意义。Design of a compact wideband dual band antenna is presented in the paper.The proposed antenna is composed of an E-shaped microstrip antenna and a microstrip dipole for dual-band operation.The lower band is also controllable.The simulated-10dB impedance bandwidths are 85MHz （2.4～2.485 GHz） and 812 MHz （5.1～5.912 GHz）,respectively.The study results show that the antenna can completely cover the required bandwidths of IEEE 802.11b/g （2.4～2.483 GHz） and IEEE 802.11a （5.15～5.825 GHz）.Details of the simulation results are presented and analyzed in the paper.In the method for designing compact wideband dual band antenna given in this paper,the two bands can be designed separately,which has great significance in engineering practice.
