摘　　要：提出一种新型的应用于无线局域网的小型化双频缝隙微带天线.该天线结构紧凑，馈电方式简单，满足无线局域网中小型化双频天线的技术要求.通过灵活调节F形槽的尺寸，可以使该天线的谐振频率工作在2.4/5.8 GHz无线局域网的应用频段.辐射方向图表明，该天线全向性能较好，增益在3.8-4.5 dBi范围内.A novel compact microstrip slot antenna for wireless communication is presented. The antenna has a compact structure and a simple feed method to satisfy technical requirements of the WLAN application. An adjustable Fshaped slot is employed to excite appropriate resonant frequencies at 2.4/5.8 GHz for WLAN. This antenna is characterized by its omni-directional radiation pattern. The gain of the antenna is 3.8-4.5 dBi.
