ANTENNA DEVICE FOR PORTABLE TERMINAL

摘要

An antenna device of the portable terminal is provided to operate in the various frequency bandwidths while using one antenna. The antenna device of the portable terminal comprises a dielectric substrate(101), a radiation patch(113), the first radiation pattern(115), the second radiation pattern(117) and a meander line radiation pattern(119). The via holes(111) are formed in dielectric substrate. The patch radiator is adhered on the dielectric substrate and is connected to the via hole. The first radiation pattern of the ring shape is formed on the dielectric substrate. A portion of the first radiation pattern is connected to the radiation patch. The second radiation pattern of the ring shape is formed on the dielectric substrate. A portion of the second radiation pattern is connected to the radiation patch. The meander line radiation pattern is formed on the dielectric substrate and is connected to the second radiation pattern.
