main antenna 230 according to the present invention is electrically connected to thefirst RF module 202 that processes Tx/Rx signals with respect to themain antenna 230. Asub-antenna 240 is electrically connected to thesecond RF module 203 or a Bluetoothmodule 204 through aswitch 220. Theswitch 220 is controlled by thecontroller 201 and may be implemented using a known Single Pole, Double Throw (SPDT) switch. - The

For example, when the mobile terminal performs a Bluetooth function, thecontroller 201 controls theswitch 220 such that thesub-antenna 240 is connected to the Bluetoothmodule 204. However, when the mobile terminal does not perform the Bluetooth function, thecontroller 201 controls theswitch 220 such that thesub-antenna 240 is connected to thesecond RF module 203 and thesub-antenna 240 can operate as a diversity antenna. - A
matching circuit 221 may be provided on a feed line between theswitch 220 and thesecond RF module 203. Similarly, amatching circuit 222 may be provided on a feed line between theswitch 220 and the Bluetoothmodule 204.

sub-antenna 240 is set to operate in 2.25 GHz band between the 2.4 GHz band used by the Bluetooth antenna and the 2.1 GHz band used by the main antenna. That is, under the control of theswitch 220, thesub-antenna 240 using 2.25 GHz band operates as the diversity antenna using the 2.1 GHz band or the Bluetooth antenna using the 2.4 GHz band through thematching circuit 221 or thematching circuit 222, respectively. - However, the method of using the matching circuit according to the present invention is not limited to the specific case described above. For example, the
sub-antenna 240 may be set to operate in the frequency band used by the Bluetooth antenna, and a matching circuit is provided only on the feed line between thesub-antenna 240 and the second RF module such that the matching circuit performs frequency matching only when thesub-antenna 240 is used as the diversity antenna. - A
display unit 205, amemory unit 206, a COder-DECoder (CODEC) 207, akey input unit 208, amicrophone 211, and aspeaker 210 are well-known components, and thus their description will be omitted for conciseness. - The antenna apparatus according to the present invention can allow the sub-antenna, which is used for the auxiliary function, to selectively operate as the diversity antenna, so that it does not require a separate diversity antenna.
