Problems solved by technology

[0010] However, in a small mobile communication terminal, even if two antennas are used for the diversity effect, it is difficult to obtain a sufficient space diversity effect
In addition, the use of two antennas and two RF receivers in the mobile communication terminal also prevents miniaturization, integration, and increases the cost of the mobile communication terminal

Embodiment Construction

[0021] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, well-known functions or constructions will not be described in detail for conciseness.

[0022] A mobile communication terminal according to an embodiment of the present invention includes two multi-band antennas, and each antenna can receive GPS signals and CDMA signals. The mobile communication terminal selects a strong signal from two signals received by the two multi-band antennas, and transmits the selected signal to the RF receiver.

[0023] image 3 Shown is the structure of a CDMA mobile communication terminal with GPS and diversity functions according to an embodiment of the present invention. Such as image 3 As shown, the mobile communication terminal includes first and second GPS / CDMA multi-band antennas 310 and 312, first and second power detectors 320 and 322, comparator 330, switch 340, GPS / CDMA RF receiver 3...

Abstract

A diversity apparatus for a mobile communication terminal with a GPS function. The diversity apparatus comprises: a first multiband antenna with a first reception polarization characteristic, for receiving a combined RF signal of a GPS signal and a mobile communication signal; a second multiband antenna with a second reception polarization characteristic distinguished from the first reception polarization characteristic, for receiving a combined RF signal of a GPS signal and a mobile communication signal; and a switching diversity unit for selecting one of the RF signals received by the first and second multiband antennas.

Description

technical field [0001] The present invention generally relates to mobile communication terminals, and in particular to a receiving diversity device and method for mobile communication terminals. Background technique [0002] Mobile communication terminals such as CDMA (Code Division Multiple Access) cellular phones / PCS (Personal Communication Services) mobile terminals, handheld phones, or IMT-2000 (International Mobile Telecommunications 2000) terminals that transmit and receive information using RF (Radio Frequency) signals . In particular, advanced mobile communication terminals are equipped with GPS (Global Positioning System) receivers for receiving absolute time information for world time synchronization and positioning information for calculating longitude / latitude from GPS satellites. In addition, the mobile communication terminal also has a separate or common antenna for standard communication and GPS communication. [0003] figure 1 It shows the structure of the...
