随着电子工业的迅速发展,要求微波器件具有体积小、重量轻、稳定性好、频带宽等特点.微带器件基本上能满足以上要求,但它的缺点之一是插入损耗较大.为了降低铁氧体微带器件的插入损耗,需要减小基片的介电损耗、磁损耗、辐射损耗、导体的欧姆损耗,以及在器件设计上必须考虑到合? With the rapid development of the electronics industry, microwave devices are required to have the characteristics of small size, light weight, good stability, wide frequency band, etc. Microstrip devices basically meet the above requirements, but one of its drawbacks is that the insertion loss is large. Reduce the insertion loss of ferrite microstrip devices, the need to reduce the substrate dielectric loss, magnetic loss, radiation loss, ohmic loss of the conductor, and the device design must be considered together?
