Abstract

Provided is an internal antenna module for receiving an FM frequency and a bluetooth frequency, which is built in a terminal to promote miniaturization and slimness of the terminal. The internal antenna module of the present invention comprises: a polyhedral chip antenna where a first emitter pattern and a coupling pattern are formed; a flexible printed circuit board where a first conductive pad connected to the first emitter pattern, a second conductive pad connected to the coupling pattern of the chip antenna, and a second emitter pattern connected to the first emitter pattern, are formed; ; and a signal switching unit which is formed between the second conductive pad and a ground, wherein the switching unit blocks either one of a first frequency band signal or a second frequency band signal which are received through the chip antenna and the flexible printed circuit board from passing the ground.

Description

technical field [0001] The present invention relates to a built-in antenna module, more specifically, to a built-in antenna module of a terminal device. Background technique [0002] With the development of mobile communication terminal equipment, people can make and receive calls anytime and anywhere, which brings great convenience to real life. In addition, with the continuous expansion of mobile communication terminal users, various functions beneficial to real life have been added to these mobile communication terminals. Among these functions, the fastest growing one is the multimedia function. At present, there are endless mobile communication terminal devices capable of generating and playing multimedia. That is, such a mobile communication terminal is no longer a simple communication tool, but a portable telephone terminal having various entertainment functions and auxiliary functions. Users can use one terminal device to watch movies, listen to music, send text me...
