摘要
文中提出了一种具有光子带隙特性的多层结构,由方形金属构成的周期阵列位于介质衬底的正中.此结构与传统的微带电路完全兼容,制作时无需在介质衬底中打孔,同时保持了接地地板的完整性.文中比较了阵列平而处于不同位置时的带隙特性,然后通过改变阵列形式来改善带隙特性.文章的最后说明了该结构的一种应用方式.
This paper presents a sandwich structure of photonic bandgap (PBG), in which a periodic pattern of square metal pads is printed in the midmost of the substrate. It is compatible with the conventional microstrip circuits. Neither drilling nor suspending the substrate is required, and the integrality of the ground plane is also kept. Several circuits with different pattern of periodic lattice are compared, and potential applying way is demonstrated.
