Patent attributes
An antenna arrangement for a portable communication apparatus includes a main antenna connectable to an antenna input, a receive antenna connectable to an antenna output, an external antenna connector for receiving a terminal of an auxiliary antenna, an antenna detector arranged to detect the terminal when it is connected to the external antenna connector, a switch adapted to connect either the receive antenna or the external antenna connector to the antenna output, and a DC voltage network. The DC voltage network is connected to the switch and is arranged to automatically control the switch to connect the external antenna connector to the antenna output and disconnect the receive antenna from the antenna output, when the terminal is connected to the external antenna connector.
