摘要
目前,无线传感器网络主要采用ZigBee协议,工作频率为2.4 GHz,针对这一应用需求,本文设计了工作在2.4 GHz的小型化矩形开槽微带贴片天线。通过曲流技术和探针馈电,缩小了天线尺寸,满足无线传感网节点小型化需求。天线长2.9 cm,宽2.9 cm,与波导波长比值为0.4,在2.4 GHz频段下,波导波长为7.0 cm。天线具有较好的辐射性能,-10 dB带宽大致覆盖2.38 GHz~2.404 GHz,辐射增益全部高于0 dBi,在工作频段(2.4 GHz)增长为最高值,达到6 dBi。
At present,wireless sensor networks mainly use ZigBee protocol,and the working frequency is 2.4 GHz.According to this application requirement,a miniaturized rectangular slotted microstrip patch antenna working at 2.4 GHz is designed in this paper.Through meander technology and probe feeding,the antenna size is reduced to meet the needs of miniaturization of wireless sensor network nodes.When the antenna works at 2.4 GHz,its guided wave length is 70 mm and the antenna size is 29 mm×29 mm,both length and width are 0.4 times of the guided wave wavelength.The-10 dB bandwidth of the antenna is 24 MHz(2.38 GHz-2.404 GHz),and the radiation characteristics of the antenna are good.Within the-10 dB bandwidth,the radiation gain is greater than 0 dbi,and the maximum value is 6dbi at the center frequency of 2.4 GHz.
