There is disclosed an antenna arrangement having a parasitic conductive loop (1) and at least one active radiating element (9). The conductive loop (1) comprises first and second electrically conductive passive radiating elements (2, 3) each with first and second ends. The first ends of the passive radiating elements are each connected to ground, and the second ends of the radiating elements are each connected respectively to mutually discrete metalized surface regions (8) of a dielectric block (7). The at least one active radiating element (9) is not conductively connected to the passive radiating elements (2, 3). The passive radiating elements (2, 3) are configured to be fed parasitically by the at least one active radiating element (9). The antenna arrangement has excellent resistance to detuning and can be located in different regions of a PCB substrate without significantly affecting performance. Further, the antenna is small in size and may be arranged for dual band operation.
