Description

technical field

[0001] The present invention relates to built-in antennas for handheld devices, and more particularly, to built-in antennas for handheld devices and design methods thereof, wherein inductive and / or capacitive elements (hereinafter referred to as "L / C" elements) and built-in antennas The slot line is connected, or the connected L / C element is moved along the slot line, or an L / C element having a predetermined inductance / capacitance value is connected or disconnected, thereby easily matching the resonance frequency. Background technique

[0002] In recent years, with the popularity of portable handheld devices such as portable phones, handheld digital assistants (PDAs) and wireless notebook computers, consumers' demands for terminals with different functions and designs are increasing. As a result, portable wireless terminals are not only being miniaturized, lightened and simplified gradually, but also the importance of design becomes more significant as their ...
