Abstract:
1. An antenna arrangement operable to transmit/receive in a first communications band and a second communications band, comprising: a ground plane; a first conductive element for transmitting/receiving; a second conductive element separate from the first conductive element and the ground plane and having, at a first position that is closest to the first conductive element, a first inductive portion that is separated from the first conductive element and having, at a second position that is closest to the ground plane, a second capacitive portion that is separated from the ground plane; and a switch element for connecting/disconnecting the second conductive element to the ground plane, wherein, the first conductive element, when the switch element disconnects the second conductive element from the ground plane, is operable to transmit/receive in a first communications band and is inoperable to transmit/receive in a second communications band and the first conductive element, when the switch element connects the second conductive element to the ground plane, is operable to transmit/receive in the second communications band and inoperable to transmit/receive in the first communications band.
