Embodiment Construction

[0037] Hereinafter, a mobile communication system having a multi-band antenna according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The following description omits descriptions of well-known constructions and functions in order to simplify the description of the present invention.

[0038] Figure 10 A schematic diagram including a block diagram is shown illustrating the structure of a mobile communication system with a multi-band antenna according to a first embodiment of the present invention. refer to Figure 10 , the multi-band antenna 12 and the housing of the mobile communication terminal 10 are assembled together. Furthermore, the multiband antenna 12 is connected to a matching circuit 40, which is connected to an electric wave path switch (hereinafter, referred to as "switch") of the band splitter / combiner section. The band splitter includes switch 45 , splitter 50 , CDMA duplexer 60 and...

Abstract

A mobile communication system has a multi-band antenna capable of receiving and processing signals of GPS, CDMA, and PCS bands. In the system, a GPS processing section receives a signal of a first frequency band, so as to generate global positioning information. A communication signal processing section receives signals of a second frequency band lower than the first frequency band and a third frequency band higher than the first frequency band, demodulates the received signals. A multi-band antenna receives and transmits signals of multiple frequency bands including the first to third frequency bands. A frequency band separator section connected between the multi-band antenna and the GPS processing section and communication processing section supplies the signal of the first frequency band to the GPS processing section. A control section controls the GPS processing section and the communication processing section.

Description

technical field [0001] The present invention relates to a mobile communication system, and more particularly to a mobile communication system with a multi-band antenna, which can be used in a portable mobile communication system and can communicate smoothly in different frequency bands. Background technique [0002] The mobile communication system has a remarkable commercial development not only in Korea but also in the whole world. Throughout the world, an important step in the development of mobile communication systems is the development from analog transmission to digital transmission. On the basis of digital transmission, a mobile communication system having a dual operation mode, ie, a system that can operate in either CDMA or PCS mode, has been under development as a personal portable mobile communication system. [0003] Furthermore, according to the E911 regulations of the (US) Communications Commission (FCC), it is expected that future communication modes in the U...
