摘要

目前，超宽带天线作为各种应用中许多窄带天线的替代品而受到广泛关注。然而，可重构天线允许自己在频率、极化或方向上重新配置，以执行多种功能。本文试图设计一种用于频谱传感的超宽带矩形贴片天线。同样的设计也被用作超宽带内窄带覆盖的频率可重构天线。利用与天线相关联的几个寄生元件的各种开关配置可以实现频率重构。这种天线结构提供了3.14至10.6 GHz的可操作频率范围，使天线适合超宽带和认知无线电前端应用。设计的仿真工具是Ansoft High Frequency Structure Simulator (HFSS)软件。

Design and Analysis of a Frequency Reconfigurable Antenna for Ultra wide band and Cognitive Radio Applications

Nowadays, ultra wide band antennas gain a lot of attention as it is an alternative to a number of narrow band antennas for a variety of applications. Whereas, reconfigurable antennas allow themselves to reconfigure in terms of frequency, polarization or pattern to perform a multitude of functions. This paper attempts to design an ultra wide band rectangular patch antenna for sensing the spectrum. The same design has also been used as a frequency reconfigurable antenna for narrow band coverage within the ultra wide band. The frequency reconfiguration could be realized using the various switching configurations of a few parasitic elements associated with the antenna. This antenna structure provides an operable range of frequencies from 3.14 to 10.6 GHz that makes the antenna suitable for ultra wide band and cognitive radio front end applications. The tool used for simulating the design is Ansoft High Frequency Structure Simulator (HFSS) software.
