摘要

本文设计了一种具有频率陷波特性的小型共面波导馈电超宽带天线。所设计的天线具有双频段陷波特性。六角形星型分形负责创建以5.2 GHz为中心的缺口带，用于WLAN消光。为了避免对8.2 GHz x波段上行卫星通信系统的干扰，在馈线处采用了相反的W形分形曲线。除了两个陷波带外，六角形单极子辐射体增加了低频的匹配特性，从而使VSWR< 2的带宽达到3.1-11.2 GHz。本文还验证了一个计算陷波频率的理论公式。

Design of compact UWB hexagonal monopole antenna with frequency notch characteristics

This paper presents the design of compact coplanar waveguide fed ultra wide band antenna having frequency Notch characteristics. The designed antenna shows a dual band notch characteristic. Hexagonal star type of fractal responsible for creating notched band centered at 5.2 GHz for WLAN elemination has been used in this work. In order to avoid interference with X-band uplink satellite communication system at 8.2 GHz, an opposite W shaped fractal curve at feed line has been used. Hexagonal monopole radiator has contributed to the resultant bandwidth of 3.1-11.2 GHz with VSWR<;2 by increasing the characteristics of matching at lower frequencies with an exception of two notched bands. A theoretical formulation to calculate the notch frequency is also validated.
