【摘要】：基于天线小型化的考虑,设计了一款适用于WLAN802.11b(2.4~2.48 GHz)系统的差分小型化微带天线。该天线采用差分馈电方式,可以和差分芯片无缝连接。采用在贴片切槽方式来实现小型化,相对于传统差分微带天线,设计出的小型化差分微带天线尺寸缩小了33%左右。利用仿真软件HFSS对设计的差分小型化微带天线进行了仿真分析。数值分析结果表明:天线谐振频率约为2.45 GHz,天线增益约为7.15 d B,回波损耗约为-16.6 d B。
[Abstract]:Based on the consideration of antenna miniaturization, a differential Miniaturized Microstrip Antenna for WLAN802.11b (2.4~2.48 GHz) system is designed. The antenna uses a differential feed mode and can be connected seamlessly with the differential chip. Compared with the traditional differential microstrip antenna, the size of the Miniaturized Microstrip antenna has been reduced by about 33%. The simulation software HFSS is used to simulate the design of the microstrip antenna with differential miniaturization. The results of the numerical analysis show that the resonant frequency of the antenna is about 2.45 GHz, the antenna gain is about 7.15 D B, and the return loss is about -16.6 D B.
