A printed circuit board having a built-in antenna may include a first unit substrate, in which a ground and a first radiator are formed; a second unit substrate, which is stacked over the first unit substrate, and in which a second radiator having a frequency band different from a frequency band of the first radiator is formed; a pair of striplines, formed in the first unit substrate and connected with the ground; a first via, which connects the first radiator with the second radiator; a pair of second vias, each of which has one end connected with the pair of strip lines respectively; and a connection pattern, which connects the other ends of the pair of second vias to each other. The printed circuit board having a built-in antenna can utilize multiple frequency bands, and can be implemented in a compact size, to be applicable in compact communication devices.

Printed circuit board having built-in antenna

Disclosed herein is a dual feeding chip antenna. The dual feeding chip antenna includes a dielectric substrate. A general transmission/reception antenna component comprised of a first conductor pattern is formed on a portion of a dielectric substrate. A diversity antenna component comprised of a second conductor pattern is formed on another portion of the dielectric substrate. A first feeding terminal is formed on one end of the general transmission/reception antenna component to connect the general transmission/reception antenna component to both transmission and reception terminals. A second feeding terminal is formed on one end of the diversity antenna component to connect the diversity antenna component to the reception terminal.

Dual feeding chip antenna with diversity function

Disclosed herein is a chip antenna. The chip antenna has a base block, and primary and second conductor lines. The base block is comprised of opposite top and bottom surfaces and side surfaces between the top and bottom surfaces, and made of one of dielectric and magnetic substances. The primary conductor line is formed at a portion of the base block and formed in the shape of an inverted F. The secondary conductor line is formed in a portion of the base block and formed in the shape of an inverted L. The primary and secondary conductor lines are connected in parallel with each other.

Chip antenna

An antenna and a manufacturing method therefor are disclosed, in which the sensitivity characteristic of the dual band antenna utilizing a plurality of frequency bands is improved, and at the same time, the antenna can be miniaturized. A first cylindrical body around which a primary coil is spirally wound is inserted into a second cylindrical body around which a secondary coil is wound. A projected portion of the primary coil is electrically connected to the secondary coil , thereby forming a dual band antenna
