INTERNAL ANTENNA

摘要

An internal antenna is provided to widen a desired resonant frequency easily by having a resonant frequency of a wide-band. An internal antenna includes a first dielectric block(200), and a second dielectric block(210). A first radiator pattern is formed on the first dielectric block. A second radiator pattern(230) is formed on the second dielectric block. The second dielectric block is horizontally coupled to an upper plane of the first dielectric block. An end of the first radiator pattern is electrically coupled to an end of the second radiator pattern. A bottom plane of the second dielectric block is coupled to an upper plane of the first dielectric block. An area of the bottom plane of the second dielectric block is larger than an area of an upper plane of the first dielectric block.
