Abstract

An antenna arrangement (200) and communication device (500) using the antenna arrangement connect a plurality of transceivers (302, 304) to a plurality of antenna elements (314, 316) and switches connections between the transceivers and the antenna elements depending on which transceiver has primary transmit control. The antenna elements include a transmit antenna element (316) and a monitoring antenna element (314). The transceiver having primary transmit control is connected to the transmit antenna element and the transceiver not having primary transmit control is connected to the monitoring antenna element.

Dependent claims

An antenna arrangement, comprising:

first and second transceivers each configured to operate according to different first and second air interfaces, respectively, wherein only one of the first and second transceivers can have primary transmit control at a time;
a diversity antenna element coupled to both the first and second transceivers;
a transmit antenna element;
a monitoring antenna element;
a switching circuit that selectively couples the first and second transceivers to the transmit antenna element and the monitoring antenna element according to:
when the first transceiver has primary transmit control the switching circuit couples the first transceiver to the transmit antenna and the second transceiver to the monitoring antenna;
and
when the second transceiver has primary transmit control the switching circuit couples the second transceiver to the transmit antenna and the first transceiver to the monitoring antenna.

5 more elements

A mobile communication device, comprising:

first and second transceivers each configured to operate according to different first and second air interfaces, respectively, wherein only one of the first and second transceivers can have primary transmit control at a time;
and
a switching circuit that selectively couples the first and second transceivers to a transmit antenna element and a monitoring antenna element such that when the first transceiver has primary transmit control the switching circuit couples the first transceiver to the transmit antenna element and the second transceiver to the monitoring antenna element, and when the second transceiver has primary transmit control the switching circuit couples the second transceiver to the transmit antenna element and the first transceiver to the monitoring antenna element.
