Abstract
The invention provides for antenna apparatus having antenna members extending parallel to a ground plane, which members are L-shaped and can be provided in advantageously miniaturized form. Two such antenna members can be provided on the same ground plane so as to achieve antenna diversity and a switch mechanism is provided for switching between the antenna member in a receive mode, and for switching to only one of the antenna members for operation of the apparatus in a transmit mode. The switch mechanism is arranged to ground a feed connector of the antenna member that is not selected for transmission or reception so as to render that antenna member passive.
