摘　　要：针对车载无线通信系统对双频微带天线的需求,提出了一种应用于WLAN/V2X频段的双频微带贴片天线,主要由2个残缺的椭圆环组成,利用2个残缺椭圆环的组合,可以实现天线的双频特性。该双频贴片天线可同时工作于无线局域网(Wireless Local Area Network,WLAN)的2个频段(2.4~2.4835 GHz,5.15~5.825 GHz)和车用无线通信技术(Vehicle to X,V2X)频段(5.905~5.925 GHz)。仿真结果表明,双频微带贴片天线在低频段和高频段的相对带宽分别为19.6%(2.3~2.8 GHz)和17.1%(5.08~6.03 GHz)。同时,天线在工作频段内的辐射特性良好,能够满足WLAN和V2X的通信要求。For the application requirements of dual-band microstrip antenna in vehicle wireless communication system,a vehicular dual-band microstrip patch antenna for WLAN/V2X is proposed.The proposed antenna mainly composed of two incomplete elliptic rings(IER),and the dual band characteristic of the antenna can be realized by the combination of the IER.The proposed vehicle antenna can generate two different impedance bandwidths to cover WLAN bands(2.4~2.4835 GHz,5.15~5.825 GHz)and V2X band(5.905~5.925 GHz).The simulated results show that the relative bandwidth of antenna of low and high frequency band is 19.6%(2.3~2.8 GHz)and 17.1%(5.08~6.03 GHz),respectively.Meanwhile,the good radiation characteristics of antennas are shown in the operating frequency band,which can meet the requirement of communication in WLAN and V2X.
