Abstract

Devices (1) comprising antennas (2) with conductive planes (201-202) with slots (205) comprising open ends and closed ends for exchanging radio frequency signals are provided with reactance circuits (203) coupled to the conductive planes (201-202) in parallel to the slots (205) to be able to tune the antenna (2) to a predefined operating frequency (band) by adjusting frequency dependent characteristics of the reactance circuits (203). The reactance circuits (203) are tunable reactance circuits (203) to be tuned via base band circuits (502). The slots (205) divide the conductive planes (201-202) into mainly exchanging planes (201) and mainly coupling planes (202). Feeding points (204) are located in the coupling planes (202) between the closed ends of the slots (205) and the reactance circuits (203). The exchanging planes (201) form part of printed circuit boards or other laminate material comprising radio frequency circuits (501) coupled to the base band circuits (502). The reactance circuits (203) comprise variable capacitors such as switchable capacitors and/or fixed capacitors (221) coupled to variable capacitance diodes (222).
