摘要： A non-reciprocal element with three central conductors and a communication apparatus are disclosed, in which the insertion loss is small and the bandwidth is wide. Three central conductors are arranged in proximity to a ferrite thin plate in such a manner as to cross each other in a mutually electrically insulated state. A static magnetic field is applied to the ferrite thin plate by a permanent magnet. An end each of the three central conductors makes up three input/output terminals, respectively, and the other end thereof is connected to a common portion. Three matching capacitors are connected between an end each of the three input/output terminals, respectively, and the common portion. At least one of the angle between the first and second central conductors and the angle between the second and third central conductors is not more than 90 degrees.

摘要： In a coil component of the present invention, a coil member having a plurality of coil lines laminated through an insulating layer is sandwiched by hexagonal ferrite substrates, and the hexagonal ferrite substrate has anisotropy. To have the “anisotropy” means that alignment of the crystal orientation is different according to a direction of the substrate, in other words, that anisotropy is provided in the c-axis orientation of ferrite crystal grains of the hexagonal ferrite substrate. As the result of the “anisotropy”, an initial magnetic permeability is also different according to direction. By using the hexagonal ferrite substrate as a magnetic substrate to sandwich the coil member so as to form a magnetic path, the initial magnetic permeability can be maintained up to a high frequency, and a high-frequency characteristic of impedance generated by the coil lines can be improved.
摘要翻译：在本发明的线圈部件中，具有通过绝缘层层叠的多个线圈线的线圈部件被六角铁氧体基板夹持，六方晶系铁氧体基板具有各向异性。具有“各向异性”意味着晶体取向的取向根据衬底的方向而不同，换句话说，在六方晶系铁氧体衬底的铁素体晶粒的c轴取向上提供各向异性。作为“各向异性”的结果，初始磁导率根据方向也不同。通过使用六边形铁氧体基板作为磁性基板夹住线圈构件以形成磁路，可以将初始导磁率保持高达高频，并且由线圈线产生的阻抗的高频特性可以要改进
