The article presents circular ring antenna loaded with triangular shaped fractals covers wide band communication systems. The proposed antenna consists of circular ring‐shaped antenna with three concentric ring‐shaped fractals are loaded inside the ring. It is designed and provides the fractional bandwidth of about 116%. The designed modal is equipped with a ground plane antenna is loaded with parasitic elements through which the reconfigurability is achieved. The reconfigurability and notching frequency bands of antenna is achieved by placing HPND‐4005 pin diodes in the Ground plane. The maximum shift in frequency is achieved for when Diode 1 is ON condition and Diode 2 is OFF condition. Similarly, antenna provides triple notching frequencies like WLAN, WiMAX and some of the x‐band applications. The antenna provides gain of 4.5 dB at different switching conditions and covers frequency applications like LTE 2300 (2.3‐2.4 GHz), WiBro (2.3‐2.39), RFID (2.44‐2.45 GHz), ISM (2.45‐2.48 GHz), WLAN (5.15‐5.35 GHz), Mobile and satellite applications (7.25‐7.37 GHz) and also mobile communication applications (8.02‐8.2 GHz) and some of the x‐band applications.

具有陷波带特性的三角形分形负载可重构天线

这篇文章提出了装有三角形分形的圆环形天线,覆盖了宽带通信系统。拟议的天线由圆环形天线组成,环形天线内部装有三个同心的环形分形。它经过设计,可提供约116%的分数带宽。设计的模态装有接地平面天线,天线上装有寄生元件,通过寄生元件可实现可重构性。通过将HPND-4005引脚二极管放置在接地层中,可以实现天线的可重配置性和陷波频段。当二极管1处于导通状态而二极管2处于截止状态时,可以实现最大频率偏移。同样,天线可提供三倍陷波频率,例如WLAN,WiMAX和某些x波段应用。天线的增益为4。
