摘要

共面波导(CPW)馈电槽天线由于制造简单和易于与有源器件集成而具有吸引力。本文对不同介质基板的cpw馈电缝隙天线阵列进行了建模。所测试的天线阵列由14个矩形cpw馈电槽组成，这些槽以均匀距离λg放置。阻抗互感器用于将阵列的阻抗转换为50Ω阻抗。平面反射板，尺寸与阵列尺寸相同，放置在距槽距λ0/4处。所有被测天线阵列的中心频率为17.1 GHz。仿真结果显示了介质常数和衬底高度对天线阵辐射方向图的影响。

Study of dielectric substrate effect on modelling CPW-fed slot antenna arrays

Coplanar waveguide (CPW) fed slot antennas are attractive due to fabrication simplicity and ease of integration with active devices. In this paper, the modelling a CPW-fed slot antenna arrays with different dielectric substrates is presented. The examined antenna array consists of 14 CPW-fed slots of rectangular shape that are placed at uniform distance λg. The impedance transformer is used to convert array's impedance into 50Ω impedance. The plane reflectors plate, with dimension same as array's dimensions, is placed at distance λ0/4 from slots. The center frequency of all examined antenna arrays is 17.1 GHz. Presented simulated results show how dielectric constant and height of substrate influence radiation pattern of proposed antenna array.
