摘要

本文提出了一种采用宽波束宽度基片集成波导(SIW)缝隙天线的双频平面相控阵。所提出的天线是在单层基板上制造的，其背面完全覆盖有金属接地。讨论并实现了槽段的程序。基于SIW的双频天线由SIW顶层的单槽组成。采用插入馈电的SIW天线将微带TEM模式转换为SIW TE10。研究了单元件的单元胞分析，分析了它们的阻抗和辐射方向图特性，以验证ku波段的波束扫描特性。通过改变槽角对单单元进行参数化分析。分析了SIW天线lx2和lx4的阵列结构，提高了平面相控阵系统的天线增益和指向性。

Design and Development of Substrate Integrated Waveguide based Dual Band Antenna for Planer Phased Radar Application

In this paper, a dual-band planar phased array using substrate-integrated waveguide (SIW) slot antenna with wide beam width is presented. The proposed antenna is fabricated on a single layer substrate, which is fully covered with a metal ground on the back. The procedure for slot section is discussed and implemented. The SIW based dual band antenna consists of single slot on top layer of the SIW. The SIW antenna fed with an inset feed transforming micro-strip TEM mode to SIW TE10. Unit cell analysis with single element is studied and analyzed in terms of their impedance and radiation pattern characteristics to validate beam scanning characteristics in Ku-band. Parametric analysis of the single element is done by changing the slot angles. Arrays of the SIW antennas lx2 and lx4 are also analyzed which improves gain and directivity of antenna for planar phased array systems.
