摘要

本文介绍了利用电磁带隙(EBG)结构实现频率和方向图可重构。第一种结构是用于波束转向配置的方向图和极化可重构天线。该天线采用一组EBG结构来控制方向图可重构性。第二个应用是EBG用于带阻抑制,其中EBG被设计为抑制和控制信号传输到天线。在这个概念中,设计了超宽带天线,并使用EBG结构来阻止信号的传输。EBG被设计成不同的尺寸。结果表明,在特定的EBG结构下,信号传输被阻止向UWB天线传播,并且在该特定频率下不发生辐射。

Frequency and Pattern Reconfigurable Antenna using Electromagnetic Band Gap Structure
This paper presents the use of electromagnetic bandgap (EBG) structure for frequency and pattern reconfigurability. The first structure is the pattern and polarization reconfigurable antenna for beam-steering configurations. The proposed antenna consists of a group of EBG structure to control the pattern reconfigurability. The second application is the use of EBG for band stop rejection where the EBG is designed to suppress and control the signal transmission to the antenna. In this concept the UWB antenna is designed and the EBG structure is used to stop the signal transmission. The EBG is designed at different sizes. The results showed that at certain EBG structure the signal transmission was prevented from propagating to the UWB antenna and no radiation occurred at that particular frequency.
