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.

Abstract:

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.

Key words: coupling feed, dual-frequency antenna, microstrip antenna, miniaturization
