An apparatus and method for adjusting an operating frequency of a multi-band antenna and a system supporting the same in a wireless communication system are provided, in which a plurality of shorting pins spaced from a radiation patch by difference distances, and a switch connects one of the shorting pins to the radiation patch.

Multi-band antenna and apparatus and method for adjusting operating frequency of the multi-band antenna in a wireless communication system

An antenna device of a mobile communication terminal is provided, the device including at least one radiation pattern and at least one magneto dielectric module or dielectric module installed in a selected position on the radiation pattern to tune one or more resonance frequencies of the radiation pattern according to resonance frequencies required for the terminal. The radiation pattern is selected from among one or more radiation patterns fabricated according to a usable frequency band. The one or more radiation patterns each include one or more resonance frequencies. The magneto dielectric module is selected from among one or more magneto dielectric modules fabricated for controlling the one or more resonance frequencies of the one or more radiation patterns. The dielectric module is selected from among one or more dielectric modules fabricated for controlling the one or more resonance frequencies of the one or more radiation patterns.

Antenna device of mobile communication terminal

A built-in antenna apparatus for a electronic device is provided. The antenna apparatus comprises a PCB with conductive and non-conductive areas. An antenna radiator is disposed at the non-conductive area of the PCB; the antenna radiator has a feeding portion and at least a first radiating portion configured in a first pattern branched from the feeding portion and has an end portion electrically connected to the conductive area. At least one capacitor is electrically connected in series within the first radiating portion. A resonant frequency of the first radiating portion is a function of a capacitance value of the at least one capacitor. The antenna can be provided in a smaller size for a given frequency band due to the capacitance. A second antenna radiator branched from the feeding portion can also be provided for operation at a different frequency band.

Built-in antenna for electronic device

A method for fabricating an antenna device of a mobile communication terminal, the method including selecting radiation patterns according to a usable frequency band, selecting and fabricating magneto dielectric modules for adjusting resonance frequencies of the selected radiation patterns, selecting and fabricating dielectric modules for adjusting resonance frequency of the selected radiation patterns, selecting and fabricating a radiation pattern having a number of resonance frequencies required for the terminal from among the radiation patterns selected in the pattern selection step, and selecting at least one of the magneto dielectric modules and the dielectric modules and installing it in the radiation pattern to tune a resonance frequency of the radiation pattern to the resonance frequency required for the terminal.
