本文提出了由双传输线和耦合传输线组成的4/6端口集总元件印刷微带电路，以模拟（简并带边）DBE晶体和磁性光子晶体（MPC）来实现高阶色散行为。利用DBE单元的最大平坦色散导致微型印刷天线具有1000/9乘以1000/9的足迹，3%的带宽和4.5 dB增益。因此，发现该DBE天线接近最佳Chu-Harrington极限。它表明，DBE单元电池可以通过集总电容夹杂物进一步小型化。此外，第一次，一个简单的印刷电路实现的固定拐点（SIP）。它的实现使用简单的印刷电路，预计将允许新的延迟线和非线性器件利用这些新的SIP属性。高阶滤波器和高孔径效率的阵列设计也被提到作为DBE和MPC电路的未来应用。
This paper proposes 4/6-port lumped element printed microstrip circuits composed of dual and coupled transmission lines to realize higher order dispersion behaviors emulating the (degenerate band edge) DBE crystals and magnetic photonic crystals (MPC). Harnessing the maximally flat dispersion of DBE unit cells resulted in a miniature printed antenna with a lambda0/9 times lambda0/9 footprint, 3% bandwidth and 4.5 dB gain. As such, this DBE antenna is found to be near the optimal Chu-Harrington limits. It is demonstrated that the DBE unit cell can be further miniaturized via lumped capacitor inclusions. Also, for the first time, a straightforward printed circuit realization of the stationary inflection points (SIP) is presented. Its realization using simple printed circuits is expected to allow for new delay lines and non-linear devices harnessing these novel SIP properties. Higher order filters and high aperture efficient array designs are also mentioned as future applications of the DBE and MPC circuits.
