(57) Abstract :
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.
