摘要
天线在提高通信标准以满足现代技术驱动的产业和个人数据服务的要求方面发挥着重要作用。本文提出了一种适用于2.4GHz无线局域网的新型贴片天线。该天线具有外形新颖的散热器和改进的接地面，外形尺寸为2425mm。该天线在FR4衬底上开发，其介电常数为4.4，衬底高度为1.6mm，损耗正切为0.002，以实现更低的回波损耗。该天线在CST Microwave studio v2019积分求解器仿真软件中进行仿真，得到的结果是:VSWR为1.31，回波损耗为-17.29dB，带宽为130MHz，增益为3.93dBi，效率为82.96%。该天线适用于使用2.4GHz谐振频率的WLAN应用。
DESIGN AND DEVELOPMENT OF NOVEL PATCH ANTENNA FOR 2.4GHz WLAN APPLICATIONS
Antenna plays major role in increasing the communication standards to meet the requirements of modern technology driven industries and personal data services. In this paper a novel patch antenna for 2.4GHz WLAN applications presented. The proposed antenna has novel shaped radiator along with modified ground plane with 2425mm overall dimension. The proposed antenna developed on the FR4 substrate with dielectric permittivity of 4.4 and height of the substrate is 1.6mm and loss tangent of 0.002 to achieve lower return loss possible. The proposed antenna simulated in an integral based solver simulation software called CST Microwave studio v2019 and obtained results such as VSWR 1.31, return loss -17.29dB with bandwidth of 130MHz, gain of 3.93dBi and efficiency of 82.96%. This antenna suitable for WLAN applications which uses 2.4GHz resonant frequency.
