In devices (1) comprising antennas (2) for exchanging radio frequency signals, the antennas (2) comprise two conductive planes (21,22) which comprise two connection points (31a,32a) and which are separated by gaps (23) for separating the conductive planes (21,22) from each other and which are coupled to each other by conductive bridges (24). These antennas (2) have a sufficient antenna performance, do not require power amplifiers to be over dimensioned, do not introduce extra power consumption, have sufficient bandwidth, are low cost and can easily be manufactured. The conductive planes (21,22) carry processing circuitry (41) and interfacing circuitry (42). By introducing two further connection points (31b,32b), the gaps (23) are divided into first gaps (23a) and second gaps (23b) by the conductive bridges (24) and the antennas (2) can be used in different frequency bands. The conductive planes (21,22) may make an angle with respect to each other, to allow the antennas (2) to be shaped in dependence of device constructions. |
