ABSTRACT:
An antenna arrangement for radio communication in a first radio communication band and for communication in a second radio communication band including a multiple-resonance antenna element having a feed for connection to radio frequency circuitry; and a load connected to the feed and comprising a plurality of reactive components including a first reactive component that controls the impedance of the load for the first radio communication band and a second reactive component, separate from the first reactive component, that controls the impedance of the load for the second radio communication band wherein the plurality of reactive components of the load are configured to provide an impedance that changes between being inductive at a first frequency in the first radio communication band to being capacitive at a second frequency in the first radio communication band and that changes between being inductive at a third frequency in the second radio communication band to being capacitive at a fourth frequency in the second radio communication band.
