论文摘要
拟议的UWB天线涵盖了移动通信（GSM，EDG，UMTS（3G），LTE（4G））和无线网络（WiFi，WiMax），在从780MHz到4.22GHz的理论带宽内。 UWB天线的设计和实现在FR-4基板上，其电介电常数为4.4。它呈现出98.75％的平均分析效率和前一个带宽内的全向辐射。根据实际部分使用的SMA阻抗，阻抗激发端口固定为50欧姆。测得的结果与使用CST和ADS软件获得的结果非常吻合。从980MHz到4.2GHz定义的测量带宽的效率为94.14％。此外，实际辐射图和激发端口阻抗保持与模拟相同。
The proposed UWB antenna covers mobile communications (GSM, EDG, UMTS(3G), LTE(4G)) and wireless networks (WIFI, WiMAX), within a theoretical bandwidth defined from 780MHz to 4.22GHz. The UWB antenna is designed and realized on a FR-4 substrate with an electrical permittivity of 4.4. It presents a 98.75% average analytical efficiency and an omnidirectional radiation within the previous bandwidth. The impedance excitation port is fixed at 50 Ohm according with the SMA impedance used in the practical part. The measured results are in good agreement with those obtained using CST and ADS softwares. The measured bandwidth, defined from 980MHz to 4.2GHz, presents an efficiency of 94.14%. Furthermore, the practical radiation diagram and the excitation port impedance stay the same as that the simulation one.
