摘要： An antenna diversity system using an active antenna is disclosed. The disclosed system may include: a first antenna configured to transmit and receive a signal of a first frequency band; a second antenna configured to transmit and receive a signal of a second frequency band; and an active circuit unit implemented by active elements. In a first mode, the second antenna is operated as a passive antenna, and in a second mode, the second antenna is electrically connected to the active circuit unit and operated as an active antenna. The disclosed diversity system has the advantages of using a diversity antenna without increasing the size of a terminal, and of using an active antenna as a diversity antenna.

摘要： A multi band internal antenna is disclosed. The antenna may include a board, an impedance matching/feeding part formed on the board, and a first radiation element joined to the impedance matching/feeding part, where the impedance matching/feeding part may include: a first matching element of a particular length that is coupled to a ground, and a second matching element of a particular length that is arranged with a distance from the first matching element and is electrically coupled to a feeding point, and where the distance between the first matching element and the second matching element may vary partially. Thus, a multi band internal antenna can be provided that utilizes coupling matching to achieve wide-band characteristics even for multi-band designs.

摘要： Disclosed is an internal antenna for a headset. The disclosed antenna comprises: a substrate, which is included inside a headset body; a feeding pattern formed on the substrate; a connecting part, which is made of a metallic material and electrically connected to the feeding pattern, and a portion of which protrudes into the housing of the headset body; a hooking part, which is joined with the connecting part; and a radiator, which is inserted into the hooking part. According to an embodiment of the present invention, audio signals may be sent and received with higher efficiency, without using a chip antenna, and the antenna may be less affected by such external factors as the hand effect and head effect.
