摘要

本文详细介绍了带通滤波器的h平面基板集成波导喇叭天线。这种结构的目的是为天线提供增强增益和低半功率波束宽度。该天线具有双频特性。在简单的h面SIW喇叭天线的顶面上开一个脊状的槽。该槽充当带通滤波器，范围为21.95GHz至25.73GHz。滤波器的10dB带宽为3.78GHz。所提出的过滤器被设计成具有六个侧肋的脊柱形状。该天线在21.8GHz时增益为4.86dB，在23.68Hz时增益为5.74dB。将滤波器集成到单声道喇叭天线中是减小集总电路元件的关键技术。因此，所提出的结构是通信系统前端元件即天线和信号处理元件如滤波器的小型化版本。这些类型的天线在雷达和卫星通信中得到了应用。

SIW Based Bandpass Filter Integrated H-Plane Horn Antenna for K Band Applications

The paper presents a detailed over view of an H-plane Substrate Integrated Waveguide Horn antenna integrated with bandpass filter. The objective of this structure is to provide enhance gain and the low half power beamwidth for an antenna. The antenna shows dual band characteristics. A slot shaped in spinal form is cut at the top surface of the simple H-plane SIW horn antenna. The slot act as a bandpass filter with a range of 21.95GHz to 25.73GHz. The 10dB bandwidth of the filter is 3.78GHz. The filter proposed is designed in a spinal shape with six side ribs. The antenna has a gain of 4.86dB at 21.8GHz and 5.74dB at 23.68Hz. Integrating a filter with SIW horn antenna is key technology for reducing the lumped circuit element. Hence the proposed structure is miniaturized version of the front element of communication system i.e. antenna and the signal processing elements like filters. These types of antenna found its applications in Radar and satellite communication.
