ANTENNA PATTERN MANUFACTURING METHOD AND ANTENNA PATTERN MANUFACTURED THEREBY
The present disclosure relates to an antenna pattern in a loop shape, which is mounted in a mobile terminal, etc. and used for wireless power transmission/reception or communication, and to a manufacturing method therefor, which enables the precise formation of the line spacing (or line width) of an antenna pattern by preparing a laminated substrate having metal layers formed on both surfaces of a base substrate and forming half grooves in the first and second surfaces of the laminated substrate, respectively, through double half-etching, wherein the half grooves at least partially overlap to construct a throughhole forming a line spacing (or line width) of an antenna pattern.
The present disclosure presents an antenna pattern manufacturing method which, by forming a through hole in a metal sheet via a punching process and an etching process, enables the precise formation of the line spacing of an antenna pattern. The presented antenna pattern manufacturing method comprises forming a first half groove in one surface of a metal sheet via a punching process and a second half groove in the other surface of the metal sheet via an etching process, wherein the first half groove and the second half groove at least partially overlap to form a through hole penetrating through the metal sheet.
The present disclosure presents a portable terminal which has antennas connected to first and second transmission ends of an NFC chipset, respectively, to enable short-range communication from the top and the back of the portable terminal. The presented portable terminal comprises: the NFC chipset having the first transmission end and the second transmission end; a first antenna connected to the first transmission end and having a region disposed parallel to the top of the portable terminal; and a second antenna connected to the second transmission end and having a loop disposed parallel to the back of the portable terminal.
The present disclosure proposes a vehicle booster antenna sheet that is manufactured in the form of a sheet attached to a holder of a vehicle and enables a recognition distance of short-range communication to be extended through a coupling effect with an NFC antenna embedded in the holder. The proposed vehicle booster antenna sheet comprises a loop pattern, wherein the loop pattern at least partially overlaps a main short-range communication antenna of the holder when a vehicle booster antenna is attached to the holder.
The present disclosure presents a booster antenna for a portable terminal, which is manufactured as a sheet or a case attachable to the rear of the portable terminal and extends the recognition distance of short-range communication by being coupled to an NFC antenna embedded in the portable terminal. The presented booster antenna for a portable terminal comprises a loop pattern. When the booster antenna for a portable terminal is disposed on the rear of the portable terminal, the loop pattern partially overlaps a main NFC radiation pattern of the portable terminal to increase the NFC recognition distance of the portable terminal.
The present invention relates to a hollow swivel actuator comprising: a lower housing in which a driving motor is disposed; and an upper housing in which three gear trains and three pinion gear units for deceleration are arranged at an interval of 120 degrees, respectively, wherein a rotor worm gear for transferring an output of the driving motor is coupled through gear engagement to a ring gear integrally formed on a rotational table, so as to transfer decelerated rotational power therebetween. A hollow swivel actuator according to the present invention can obtain a great deceleration ratio by: primary deceleration between a rotor worm gear of a driving motor and a first to a third worm wheels of a first to a third gear trains; secondary deceleration between a first to a third worm gears and a fourth to a sixth worm wheels of a first to a third pinion gear units; and tertiary deceleration between a ring gear and a first to a third pinion gears, and thus can achieve a large torque increase.
