摘要

本研究提出了一种宽带选频天线罩，它可以吸收KU波段的微波，并传输更高频率的功率。该天线罩由两个不同的频率选择表面(FSS)组成。传输窗口和吸收带是通过阻抗匹配原理实现的。在保证吸波带的同时，采用无损泡沫作为介质。选择集总电阻来吸收微波而不是墨水，可以减少工艺的复杂性。经过CST Microwave Studio 2012的仿真，结果表明，在13.5 GHz ~ 17.5GHz范围内，反射系数小于- 10dB。从32ghz到39GHz的传输率超过8%。该天线罩可广泛应用于隐身飞机的通信系统中。

Analysis and design of a wideband radome with lumped resistor

In this study, a wideband frequency selective radome is represented, which can absorb the microwave of KU band, and will transmit the higher frequency power. This radome is composed of two different frequency selective surfaces (FSS). The transmission window and absorbing band are realized by the principle of impedance matching. Lossless foam is used as the medium while the absorbing band is promised. Lumped resistors are chosen to absorb microwave other than ink that can reduce the complexity of process. After simulating by CST Microwave Studio 2012, the result shows that from 13.5 GHz to 17.5GHz, reflection coefficient is lower than −10dB. And the transmittivity is more than eight percent from 32 GHz to 39GHz. This radome can be applied broadly in the communication system of stealth aircraft.
