Abstract
Disclosed is a method for tuning an antenna module in a portable wireless terminal and built-in antenna module using the same. According to the method and built-in antenna module, the built-in antenna module is provided with a plate type radiator defining a slot with a predetermined width to form a pattern. The plate type radiator is provided with downwardly protruded feed and ground pins that are spaced apart, and at least one passive element having a predetermined value is connected to the radiator to optimally tune the antenna module. Therefore, various frequency response properties of the built-in antenna module can be attained by altering such a passive element as a variable design parameter without changing the radiator. Also, this construction can take the place of a matching circuit in a signal line, such that radiation performance can be increased without insertion loss.
