| 摘 要： | 为满足室内覆盖天线在无线通讯系统多个频段的要求,采用了背馈式非对称振子结构,利用添加多寄生贴片和调节片的方法,设计了一种带有寄生贴片的多频段定向天线。通过HFSS10.0软件仿真优化,该天线覆盖了800MHz～960MHz频段(最大增益在900MHz为5.43dB),1230MHz～2230MHz超宽频段(频带宽度为:57.8%,最大增益在1830MHz为10.2dB)和2350MHz～2520MHz频带(最大增益在2450MHz为10.8dB),满足了AMPS、GSM、DCS、PCS、UMTS和WLAN频段的要求,且具有稳定的方向性。

| Abstract: | A multi-band back-fed asymmetrical element beam antenna is proposed.Multiple parasitic patches and tuning strips are added to satisfy the requirements of indoor coverage antenna in wireless communication system.The antenna is simulated and optimized by HFSS10.0 software,covering 800 MHz～960 MHz（the peak gain：5.43 dB at 900 MHz）,1230 MHz～2230 MHz（the bandwidth：57.8%,the peak gain：10.2dB at 1830 MHz）,2350 MHz～2520 MHz（the peak gain：10.8 dB at 2450 MHz）.The simulation results show that the designed antenna is suitable for AMPS, GSM, DCS, PCS, UMTS and WLAN, and its radiated direction is stable. |
