摘　　要：该文研究新型的宽频带微带天线,采用一种具有双层贴片结构的微带天线的形式,并用在探针顶端加电容性金属圆片来抵消探针感性的方法,增加了天线的工作带宽。制作适用于第二代和第三代移动通信的宽频带微带天线,测试结果显示天线具有良好的带宽特性,能够满足移动通信系统对天线的带宽要求。A novel broadband microstrip antenna is presented, Double patch configuration is employed,and a circular metal is introduced on the top of the feed probe to counteract the inductance of the probe. As a result, the bandwidth of microstrip antenna is increased. Broadband microstrip antennas suitable for second generation and third generation mobile communication are fabricated, whose measurement results show that good bandwith characteristics are obtained, which can address the need of bandwidth for the mobile communication system,
