摘要

本文提出了一种吸收/透射(A/T)天线罩。天线罩是由周期性氮化钽结构和金属频率选择表面(FSS)结构组成的双层结构。在给定的频带上充当通带滤波器的FSS。利用FSS作为全反射带内基于氮化钽结构的宽带吸收体的接地面。当入射波照射到氮化钽结构时，天线罩具有宽带吸收特性。当入射波照射到带通FSS时，天线罩具有传输特性。最终结果表明，在2.8 ~ 3.9 ghz频段，S21的信号增益大于-3dB。S11在6.8-18.7GHz频段的信号小于-5dB。

An Absorbing/ Transmissive Radome Based on Tantalum Nitride

In this paper, an absorbing/transmissive (A/T) radome is proposed. The radome is a double layer structure, which is composed of periodic tantalum nitride structure and metallic frequency selective surface (FSS) structure. The FSS acting as a pass band filter at a given frequency band. The FSS is used as the ground plane of a wideband absorber based on tantalum nitride structure within the total reflection band. The radome exhibits broadband absorbing property when the incident wave illuminate to tantalum nitride structure. The radome presents transmission characteristic when the incident wave illuminate to the band-pass FSS. The final result show that the S21 is more than -3dB in 2.8-3.9GHz. The S11 is less than -5dB in 6.8-18.7GHz.
