ABSTRACT:
A broadband antenna framework used for receiving and emitting radio signals for a mobile communication device (such as a mobile phone). The mobile communication device is provided on an upper edge of its circuit board (having a grounding surface) with an antenna, and is provided between the antenna and the circuit board with a meandering line; the meandering line is provided thereon with components containing multilayer ceramic capacitors (MLCC) or multilayer ceramic inductors (MLCI); by using the capacitors or the inductors, the coupling effect between the grounding surface and the antenna can be insulated, so that there can be sufficient distance between the grounding surface and the antenna to radiate energy, the capacitors or the inductors do not result a direct current open circuit, hence other electronic elements can be laid around an antenna.
