Abstract
In an I-conductor for the high-frequency or microwave systems, two uniform cores are disposed parallel to each other with a gap therebetween and a coil is disposed on each core in such a way that, when energized by an HF current, a magnetic circuit through the two cores is generated by way of the gap at one end of the arrangement. The magnetic field forming windings are uniform. As cores, magnetically anisotropic materials may be used.
Claims9
An I-inductor in the form of a high frequency-micro-inductor (HF inductor) for microsystems, comprising:
- adjacent cores of a magnetic permeable material, which are arranged in a rectangularly limiting plane with a gap therebetween and which are band-like and have parallel longitudinal axes and the same length and a cross-section sufficient to accommodate a predetermined magnetic flux, said cores being provided with a winding such that, upon energization of the winding, the magnetic flux generated by a turn of the winding in immediately adjacent cores extends fully in the magnetic material of the cores and the magnetic field generated in each core has a direction in which the flux in the adjacent core is amplified.
