Abstract (en)

[origin: WO2022022976A1] The invention describes a multiband loop antenna (100) which comprises a first, electrically conductive, L-shaped partial structure (110) on a first layer (151) of a printed circuit board (150). The first partial structure (110) has a first resonant frequency and a feed point (107) of the antenna (100). The multiband loop antenna (100) comprises a second, electrically conductive, L-shaped partial structure (120) on the first layer (151) of the printed circuit board (150), the second partial structure (120) being designed for a second resonant frequency. The first partial structure (110) and the second partial structure (120) are capacitively coupled to one another in a coupling region (109). Furthermore, the multiband loop antenna (100) comprises an electrically conductive first reference region (105). The first partial structure (110) and the second partial structure (120) are arranged on the first layer (151) of the printed circuit board (150) in such a way that they form a loop (109) together with the first reference region (105).
