Antenna arrangement

An antenna arrangement for use in a radio frequency (RF) communication terminal including:

• a plurality of resonators formed from a plurality of conductive wires;
• and
• a plurality of radio frequency feed channels, each feed channel being operably connected to one of the resonators at a feed point of the resonator for delivering an RF signal between the resonator and an associated radio and providing an operational frequency band,
• wherein:
• the number of the resonators is not less than the number of the feed channels,
• the resonators include mutually adjacent wires having different lengths extending from adjacent feed points,
• each of the feed channels includes a band pass filter operable to pass RF frequencies in the operational frequency band of the feed channel and an associated control device which controls an impedance of the feed channel at frequencies outside the operational frequency band, and
• coupling is provided between at least one resonator of the resonators whose feed channel is not the operational frequency band of at least one other resonator of the resonators with the at least one other resonator to enhance a resonance of the at least one other resonator.
