摘要:
A multiple cell photovoltaic device includes first and second serially connected solar cells and a conductive or dielectric selective reflection film therebetween. The thickness of the selective reflection film is chosen to reflect short wavelength light which may be absorbed by the second solar cell and to transmit long wavelength light which is not absorbed by the second solar cell and may be absorbed by the first solar cell. When the selective reflection film comprises a dielectric material, apertures are provided in the selective reflection film for serial electrical connection of the two cells.

A non-feeding element is provided with a proximity-providing gap from a feeding element, and a resonant state is generated there by capacitive coupling. The non-feeding element resonates at a frequency different from a resonant frequency of the feeding element. The feeding element and the non-feeding element have alongside-ground-terminal extending portions spaced from an edge surface at one end of a ground surface formed on the circuit board and to extend in a direction along the edge surface at the one end of the ground surface. The feeding element and/or the non-feeding element is formed three-dimensionally with a plurality of bending portions so that at least parts of the alongside-ground-terminal extending portion of the feeding element and the ground-terminal extending portion of the non-feeding element have substantially the same amount of spacing from the ground surface.

An antenna includes a base, a first radiating element, and second radiating element. The first radiating element is open at a first end thereof, is connected to a ground point at a second end thereof, and resonates in a substantially ¼ wavelength mode in a first communication frequency band. A feed line is connected between a first feed point and a predetermined position between the first end and the second end of the first radiating element. The second radiating element has a first end that is a second feed point, a second end that is connected to the ground point, and resonates in a substantially ½ wavelength mode in a second communication frequency band. A distance from the ground point to the second feed point is longer than a distance from the ground point to the first feed point.

This disclosure provides a high-frequency dielectric attachment capable of suppressing a decrease in Q value of a high frequency circuit and achieving a great adjusting effect. The high-frequency dielectric attachment is a laminate of an insulating sheet layer, adhesive layer, and a dielectric sheet layer. The insulating sheet layer forms an outermost layer of the laminate, and the adhesive layer and dielectric sheet layer are arranged in sequence below the insulating sheet layer. The width of the dielectric sheet layer is smaller than each of the width of the insulating sheet layer and the width of the adhesive layer. The adhesive layer projects beyond the dielectric sheet layer in the width direction.

A photovoltaic power device includes a P-type silicon substrate, a low-resistance N-type diffusion layer diffused with an N-type impurity in a first concentration formed at a light-incidence surface side, grid electrodes formed on the low-resistance N-type diffusion layer, a P+ layer formed on a back surface, and a back surface electrode formed on the P+ layer. The photovoltaic power device has concave portions provided at a predetermined interval to reach the silicon substrate from an upper surface of the low-resistance N-type diffusion layer, and an upper surface of a region between adjacent concave portions includes the low-resistance N-type diffusion layer. A high-resistance N-type diffusion layer diffused with an N-type impurity in a second concentration, which is lower than the first concentration, is formed in a range of a predetermined depth from a formation surface of the concave portions.

A non-feeding element is provided with a proximity-providing gap from a feeding element that receives RF power from a feeding point on a circuit board, and a resonant state is generated there by capacitive coupling. The non-feeding element is formed so as to resonate at a frequency different from a resonant frequency of the feeding element. The feeding element and the non-feeding element have alongside-ground-terminal extending portions formed so as to be spaced from an edge surface (a ground terminal) at one end of a ground surface formed on the circuit board and to extend in a direction along the edge surface at the one end of the ground surface. At least one of the feeding element and the non-feeding element is formed three-dimensionally with a plurality of bending portions so that at least parts of the alongside-ground-terminal extending portion of the feeding element and the ground-terminal extending portion of the non-feeding element have substantially the same amount of spacing from the ground surface, with a mutual gap in a thickness direction of the circuit board.
摘要:
In an antenna structure 1 in which a feed radiation electrode provided on a dielectric base member performs an antenna operation in a fundamental mode and an antenna operation in a higher-order mode with a resonant frequency higher than that in the fundamental mode, one end of the feed radiation electrode defines a feed end connected to a circuit for radio communication, and the other end of the feed radiation electrode defines an open end. The position of a capacitance-loading portion α is set in advance between the feed end and the open end of the feed radiation electrode. A capacitance-loading conductor is connected to one or both of the feed end and the capacitance-loading portion α of the feed radiation electrode. The capacitance-loading conductor forms a capacitance for adjusting a resonant frequency in the fundamental mode between the feed end and the capacitance-loading portion α.
摘要:
A surface-mounted type antenna which facilitates the realization of the widening of the frequency band, and a communication device including it. In this antenna, the strong electric-field regions of a power supplied first radiation electrode and a power non-supplied second radiation electrode are disposed adjacent to each other with a spacing therebetween, and simultaneously the high current regions of these radiation electrodes are disposed adjacent to each other with a spacing therebetween. By variably adjusting the quantity of the electric-field coupling between the strong electric-field regions of the first radiation electrode and the second radiation electrode, and by variably adjusting the quantity of the magnetic-field coupling between the high current regions of these radiation electrodes, both the quantities of the electric-field coupling and the magnetic-field coupling are set to conditions suited for the dual resonance. A superior dual resonance is thereby achieved.
