Abstract: Disclosed is an internal antenna using electromagnetic coupling that supports improved impedance matching. The antenna includes a first conductive member having one end electrically connected with a power feed point; a second conductive member separated from the first conductive member by a particular distance and electrically connected with a ground; a radiator extending from the second conductive member; and a grounding plate joined with the other end of the first conductive member. This antenna provides the advantages of adequately ensuring wide-band and multi-band characteristics while improving impedance matching properties.

Abstract: A broadband internal antenna using double electromagnetic coupling is disclosed. The disclosed antenna may include: a first conducting member electrically connected to a feeding point; a second conducting member placed at a designated distance from at least a portion of the first conducting member so as to allow a first electromagnetic coupling with at least a portion of the first conducting member, and remaining in a floating state without being coupled to a ground and the feeding point; a third conducting member placed at a designated distance from the second conducting member so as to allow a second electromagnetic coupling with the second conducting member, and electrically connected to the ground; and a fourth conducting member extending from the third conducting member, for radiating RF signals. The disclosed antenna has the advantage of providing broadband characteristics within a limited size.

Abstract: A patch antenna is disclosed. The disclosed patch antenna may include: a first radiator configured to generate a circular polarized wave; a first dielectric substrate equipped under the first radiator; a second radiator, placed under the first radiator at a designated distance from the first radiator, and configured to generate a linear polarized wave; a second dielectric substrate equipped under the second radiator; and a reflecting plate equipped under the second radiator at a designated distance from the second radiator; where the first dielectric substrate, the second radiator, the second dielectric substrate, and the reflecting plate are connected through at least one via. A patch antenna according to the present invention has the advantages of being able to generate linear polarized waves and circular polarized waves simultaneously, and of having a small size while still having a high design frequency band.

Abstract: The present invention relates to a technology for forming a patch antenna generating both linearly and circularly polarized waves at the same time, so as to reduce a propagation loss during transmission/receiving operations between a circularly polarized antenna and a linearly polarized antenna.
