摘要：

为了快速地设计一款应用于无线局域网络(WLAN)的双面结构的具有双频段、宽频带、小型化特性的偶极子天线，将偶极子贴片分别放置于介质基板的两侧，并采用微带巴伦线馈电的方式，以实现更好的宽带匹配。在偶极子的两臂分别开槽，实现小型双频特性，以满足WLAN的2.45GHz和5.49GHz的双频要求。整个天线的尺寸为28mm×44mm×1.6mm。并且利用电磁仿真软件高频结构仿真器(HFSS)和神经网络(NN)联合优化天线的尺寸，加快设计过程。仿真结果表明，当S11小于-10dB时，天线在低频和高频的带宽分别可以达到470MHz(2.29~2.76GHz)和3650MHz(4.96~8.61GHz)；当S11小于-14dB时，天线在低频和高频的带宽分别可以达到210MHz(2.36~2.57GHz)和770MHz(5.13~5.9GHz)。而且该天线的方向图具有良好的全向性，实物测量与仿真结果的一致性良好，可以满足WLAN的需要。

Abstract:

To quickly design a two-sided dipole antenna, which is used to Wireless Local Area Network (WLAN), with small size, dual-band and broadband characteristics, the dipole patch were printed on opposite sides of the dielectric substrate, and balun feed mode was used to achieve better broadband matching. Two arms of the dipole were slotted to achieve the small and dual-band characteristics, and to meet the dual-band requirements of WLAN of 2.45GHz and 5.49GHz. The size of the whole antenna is 28mm×44mm×1.6mm. And the Neural Network (NN) with electromagnetic simulation software named High Frequency Structure Simulator (HFSS) was combined to optimize the key size of the antenna and speed up the design process. The simulation results show that, when the S11 is less than -10dB, the bandwidth of the antenna in low frequency and high frequency can reach 470MHz (2.29—2.76GHz) and 3650MHz (4.96—8.61GHz) respectively; When the S11 is less than -14dB, the bandwidth of the antenna can reach 210MHz (2.36—2.57GHz) and 770MHz (5.13—5.9GHz) respectively. The pattern has good omni-direction, and the measurement and simulation results are in good consistency. The antenna can meet the requirements of WLAN.
