Disclosed is an antenna arrangement (1) that can be operated in two different working frequency ranges. The antenna arrangement consists of a radiating element (5) that has an input connection (10) and a reference potential connection (15). The radiating element (5) is resonant in both a first working frequency range and in a second working frequency range that is different from the first. It can also be selectively supplied with signals in the first or second working frequency range via the input connection (10). The reference potential connection (15) is connected to the reference potential (25) of a reference potential surface (30) by means of a first impedance (20, 35, 40). In the first working frequency range, the first impedance (20, 35, 40) is a high impedance; in the second it is a low impedance. Also disclosed is a radio device provided with said inventive antenna arrangement (1). |
