BUILT-IN ANTENNA FOR CONTROLLING RESONANT FREQUENCY

PURPOSE: A built-in antenna is provided to control the resonant frequency by using a ground slit and a variable capacity without the deformation of an antenna pattern. CONSTITUTION: A built-in antenna is installed on a mainboard(300) of a mobile terminal. A ground is formed in the mainboard of the m...

Summary:PURPOSE: A built-in antenna is provided to control the resonant frequency by using a ground slit and a variable capacity without the deformation of an antenna pattern. CONSTITUTION: A built-in antenna is installed on a mainboard(300) of a mobile terminal. A ground is formed in the mainboard of the mobile terminal. The ground is formed in the form of a meander line(310). A variable capacitor(320) is installed between the meander line and the ground. The resonant frequency of the built-in antenna is controlled according to the length of the meander line, a value of the variable capacitor, the inductance component value of the variable capacitor, or the capacitance component of the meander line.
