摘要:
A ultrathin magnetoelectric transducer and its manufacturing method are provided which enable the quality of mounting to be inspected nondestructively, and can reduce a footprint. The magnetoelectric transducer has a substrate composed of a nonmagnetic substrate, and includes bottom surface connecting electrodes whose leads have a first thickness, and side electrodes which are exposed by dicing and have the first thickness. Amore sensitive Hall element has a high-permeability magnetic substrate as the substrate, and includes the bottom surface connecting electrodes whose leads have the first thickness, and the side electrodes exposed by the dicing and having the first thickness. The bottom surface connecting electrodes of the leads with the first thickness are formed across the internal electrodes of adjacent magnetoelectric transducers with maintaining the first thickness. The side electrodes with the first thickness are formed by cutting the center between the adjacent magnetoelectric transducers.

The magnetoelectric transducer has a substrate composed of a nonmagnetic substrate, and includes bottom surface connecting electrodes whose leads have a first thickness, and side electrodes which are exposed by dicing and have the first thickness. A more sensitive Hall element has a high-permeability magnetic substrate as the substrate, and includes the bottom surface connecting electrodes whose leads have the first thickness, and the side electrodes exposed by the dicing and having the first thickness.

摘要:
A radiator is provided with a looped radiation conductor, a capacitor, an inductor, a feed point on the radiation conductor, and a dielectric block provided in a portion where the radiation conductor and the ground conductor are close to each other. At a low-band resonance frequency, a current flows through a path extending along an inner perimeter of the loop of the radiation conductor and including the inductor and the capacitor. At a high-band resonance frequency, a current flows through a path including a section extending along an outer perimeter of the loop of the radiation conductor, including the capacitor but not including the inductor, and extending between the feed point and the inductor, and a parallel resonant circuit is formed from: a capacitance between the radiation conductor and the ground conductor between which the dielectric block is provided; and an inductance of the radiation conductor.

An antenna apparatus includes a slit provided on an antenna element between first and second feed ports; and a series resonant circuit provided at a location along the slit, with a distance from an opening of the slit. When the antenna apparatus operates at a first isolation frequency identical to a resonance frequency of the series resonant circuit, the series resonant circuit is short-circuited, and only a section of the slit from its opening to the series resonant circuit resonates, thus providing isolation between the feed ports at the first isolation frequency. When the antenna apparatus operates at a second isolation frequency lower than the first isolation frequency, the series resonant circuit is open, and the entire slit resonates, thus providing isolation between the feed ports at the second isolation frequency.

An antenna apparatus includes a first feeding point and a second feeding point provided at respective positions on an antenna element. The antenna element is excited through the first and second feeding points simultaneously so as to operate as a first antenna portion and a second antenna portion simultaneously, the first antenna portion and the second antenna portion correspond to the first and second feeding points, respectively. The antenna element further includes, between the first and second feeding points, an electromagnetic coupling adjuster for making an amount of isolation between the first and second antenna portions.
摘要:
An antenna element has first and second feed ports, and is simultaneously excited through the feed ports so as to simultaneously operate as first and second antenna portions respectively, associated with the feed ports. The antenna element is excited at one of a first frequency and a second frequency higher than the first frequency. An antenna apparatus is provided with: a slit that provides isolation between the feed ports; a trap circuit that allows the slit to provide isolation at the first or second frequency when the antenna element is excited at the first or second frequency; and a reactance element that shifts a frequency at which the slit provides isolation between the feed ports, to the first frequency, when the antenna element is excited at the first frequency.
