Antenna arrangement and mobile terminal device
First Claim
1. An antenna arrangement which is operable in various mobile communication systems using different frequencies, comprising transmitter/receivers of a multi-mode phone, at least two antennas so that in an antenna arrangement consisting of two antennas the signals are transmitted so that the first antenna transmits signals of the second, third and fourth systems, and signals are received so that signals of the third system are received through the first antenna, signals of the second and fourth systems are received through the second antenna and in an antenna arrangement consisting of three antennas the signals are transmitted so that the first antenna transmits signals of the second system, the second antenna transmits signals of the fifth system, and signals are received so that signals of the second system are received through the second antenna and signals of the fifth system are received through the third antenna.

Abstract
The invention is concerned with an antenna arrangement adapted to a mobile terminal and division of frequency bands between different antennas. The antenna arrangement enables the terminal to operate worldwide in networks applying different frequency bands and technologies, as a so-called multi-band terminal. In the antenna arrangement the frequency bands of the antennas are arranged for each antenna in a way that the bands fill an optimal frequency area, thus accomplishing smaller total volume for the antennas and a good performance.
