Abstract
A built-in antenna module for a portable wireless terminal is provided. In the built-in antenna module, a mainboard, which is an RF board, has a feeding unit and a grounding unit. A radiator is disposed on one side of the mainboard and has a feed pin and a ground pin that are electrically connected to the feeding unit and the grounding unit, respectively. A conductive ground plate is disposed on the other side of the mainboard to have a predetermined height. An end of the conductive ground plate is grounded to the grounding unit of the mainboard. The distance between the radiator and the ground plate is maximized to improve antenna performance.
Claims7
A built-in antenna module for a portable wireless terminal, the module comprising:
- a mainboard being an RF board and having a feeding unit, a grounding unit, an upper surface, a lower surface opposite the upper surface, and a thickness t1;
- a radiator disposed on one side facing the upper surface of the mainboard, and having a feed pin and a ground pin electrically connected to the feeding unit and the grounding unit of the mainboard, respectively;
- a conductive layer electrically connected to the ground unit and disposed on the lower surface to add an amount up to t1 to an orthogonal distance between the radiator and the conductive layer for improving antenna performance;
- and
- a conductive ground plate disposed on the other side facing the lower surface of the mainboard and spaced a predetermined height therefrom for improving antenna performance, the conductive ground plate being electrically connected to the radiator via the ground unit and the ground pin.
