INTERNAL ANTENNA FOR LOW FREQUENCY BAND

摘要

An internal antenna for a low frequency band is provided to simplify a structure and increase a spatial efficiency by not requiring an additional unit like an earphone for implementing the low frequency band. An internal antenna for a low frequency band includes a polyhedral magneto-dielectric block(10), a radiator pattern(12) formed on the magneto-dielectric block, and a coupling pattern. The coupling pattern is formed on one or more facets of the magneto-dielectric block. One or more coupling patterns are separated from the radiator pattern on the corresponding facet. The coupling pattern couples the flow of the current inputted into the radiator pattern.
