摘要

无线通信通过人机交互和机器-机器交互来处理各种实时应用，探索了信息交换的新时代。这就造成了处理高带宽智能应用的频谱稀缺性。认知无线电是一种通过动态频谱接入(DSA)来管理频谱拥塞的先进方法。通过机会扫描，允许未授权的从用户访问主授权用户未使用的频谱。这引出了无线传感器网络对超宽带天线的需求，以便在扫描期间探索每一个可能的空闲信道机会。针对无线认知无线传感器网络(WCRSN)，提出了一种新型超宽带天线，使其能够按照FCC标准扫描最大的射频频谱。天线在3.3-11.5 GHz的宽频谱范围内提供匹配的阻抗带宽，在整个频率扫描中具有可持续的4.0 dBi高增益和双向辐射特性。

Wideband Sensing Antenna for Smart Cognitive Radio Applications

Wireless communication explores new era of ease of information exchange through human-machine and machine-machine interaction to deal various real time applications. This has created a great spectrum scarcity to deal high bandwidth smart applications. The cognitive radio is an advance approach to manage spectrum congestion through dynamic spectrum access (DSA). The unlicensed secondary users are being allowed to access unutilized spectrum of primary licensed users through opportunistic scan. This elicits the need of an UWB antenna for wireless sensor networks to explore every possible vacant channel opportunity during scan. A novel UWB antenna is proposed here for wireless cognitive radio sensor network (WCRSN) to scan maximum RF spectrum as per FCC standard. Antenna offers matched impedance bandwidth for wide spectrum range from 3.3-11.5 GHz with sustainable 4.0 dBi high gain and bidirectional radiating properties for the entire frequency sweep.
