US 2006/0066490 A1 · Built-in antenna module for portable wireless terminal

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.
