摘要

本文讨论了用于超宽带和X波段应用的单极天线设计。将两个矩形贴片与修改后的矩形接平面合并形成贴片，阻抗带宽为2.82GHz-15.73GHz。天线还能够消除三个干扰频段，即微波接入无线互操作性(WiMAX/C频段:3.30GHz - 3.80GHz / 3.80GHz - 4.20GHz)，无线局域网(WLAN: 5.150GHz - 5.825GHz)和下行卫星系统(DSS: 7.25GHz - 7.75GHz)。这些干扰带通过使用射频PIN二极管进一步重新配置，以便每个干扰可以单独控制。WiMAX的陷波带是通过在辐射贴片上刻蚀圆形槽来实现的，WLAN是通过在馈线附近使用c形寄生桩来实现的，DSS的陷波带是由于在辐射贴片上刻蚀t形槽而实现的。设计的天线具有良好的频率、空间和时域分析能力，辐射方向图稳定，最大增益4.85dBi，辐射效率89%，脉冲响应可接受，群延迟≤0.20ns。上述设计的全部特征和结果为无线通信系统中的许多应用提供了设计天线。

High Rejection Plus Shape Radiating Patch Triple Notched UWB/X Band Reconfigurable Monopole Antenna for Imaging and Close Range Radar Applications

This research article discusses monopole antenna designed for UWB (Ultrawideband) and X band applications. Patch is formed by merging two rectangular patches and modified rectangular ground plane leading to impedance bandwidth of 2.82GHz-15.73GHz. Antenna is also capable of removing three interfering bands namely Wireless Interoperability for Microwave Access (WiMAX/C band: 3.30GHz - 3.80GHz / 3.80GHz - 4.20GHz), Wireless Local Area Network (WLAN: 5.150GHz - 5.825GHz) and Downlink Satellite System (DSS: 7.25GHz - 7.75GHz). These interfering bands are further reconfigured by using RF PIN diode so that each interference can be controlled individually. WiMAX notched band is achieved by etching circular slot on radiating patch, WLAN is obtained by using C-shaped parasitic stubs near feed line and DSS notched band is due to T-shaped slot also etched on radiating patch. Designed antenna offers good frequency, space and time domain analysis with stable radiation pattern, maximum gain of 4.85dBi, radiation efficiency of 89%, acceptable impulse response and group delay ≤0.20ns. The entire above designed features and results offers designed antenna for number of applications in wireless communication system.
