小型双陷波超宽带印刷天线

一种小型双陷波超宽带印刷天线

内容简介：为了抑制超宽带天线频率范围内WLAN系统的工作频率5.15GHz～5.825GHz和卫星通信系统中X波段的下行频率5.15GHz～5.825GHz,提出了一种小型双陷波超宽带印刷单极子天线。该天线采用微带线馈电,在辐射贴片上开三个半圆环槽,使得天线在上述两个频段处回波损耗大于-10dB,从而避免了与超宽带通信系统的相互干扰。

Abstract：In order to inhibit the frequency in 5.15 GHz-5. 825 GHz for WLAN and 7.25 GHz-7.75 GHz for downlink of X-band satellite communication systems of the UWB, a compact printed microstrip-fed monopole ultrawideband antenna with double notched bands is proposed. Three semicircular half-wavelength slots are cut in the radiating patch to gener- ate two notched bands and to make sure that the return loss is larger than --10 dB, thus it can avoid the interference with the UWB communication system.
