Abstract
A multiband loop antenna includes a first, electrically conductive, L-shaped partial structure on a first layer of a printed circuit board. The first partial structure has a first resonant frequency and a feed point of the antenna. The multiband loop antenna includes a second, electrically conductive, L-shaped partial structure on the first layer of the circuit board. The second partial structure is configured for a second resonant frequency. The first partial structure and the second partial structure are capacitively coupled to one another in a coupling region. The multiband loop antenna includes an electrically conductive first reference region. The first partial structure and the second partial structure are disposed on the first layer of the circuit board in such a way that they form a loop together with the first reference region. A household appliance including a communication unit having the multiband loop antenna is also provided.
