Abstract: A multiband antenna (1200, 1300) comprising a substrate (1203, 1303) having a first surface (1204) and a second surface (1307). A first conductive plate (1210) is located on the first surface (1204) of the substrate (1203), the first conductive plate comprising a first conductive region (1201), which is couplable to ground by a shorting element (1206), and a second conductive region (1202). The first conductive region (1201) and second conductive region (1202) are located so as to define a gap (1205) therebetween. The antenna also has a second conductive plate (1308) on the second surface (1308) of the substrate (1303). The second conductive plate (1308) is coupled to a signal terminal (1314a) of a feeding port (1314) and positioned in order to provide capacitance with the first conductive region (1201). The antenna also has a third conductive plate (1309) on the second surface (1307) of the substrate (1303). The third conductive plate (1309) is positioned in order to provide capacitance with the second conductive region (1202), and a connecting conductor (1512, 1612) configured to electrically couple the third conductive plate (1309) to the second conductive region (1202).
