Abstract: Antenna assembly may include a dielectric substrate having a relative dielectric constant (?r) of greater than one. The dielectric substrate may include a first branch that comprises a first antenna pattern and a first ground point for connecting the first antenna pattern to a first ground. The dielectric substrate may include a second branch that may include a second antenna pattern and a second ground point for connecting the second antenna pattern to a second ground. Each antenna pattern may thereby be configured to transmit and/or receive signals within a predetermined frequency band when said antenna assembly is in use.

Abstract: An antenna device for a portable radio communication device adapted for receiving radio signals comprises an internal radiating element (10) comprising at least one feeding portion (21, 22) connected to a receiver circuit (40). The radiating element (10) comprises an electrical impedance (30) that is controllable in dependence on the desired frequency range of the received signals, wherein the feeding portion (21, 22) is connected to a feeding input (40a, 40b) on the receiver circuit and the control input of the controllable electrical impedance (30) is connected to an output (40c) on the receiver circuit (40) intended for the control of the VCO resonance frequency of the receiver circuit.
