ANTENNA ASSEMBLY, PACKAGED ANTENNA, CIRCUIT BOARD ASSEMBLY AND ELECTRONIC DEVICE

The present application relates to an antenna assembly, a packaged chip, a circuit board assembly and an electronic device. The antenna assembly comprises: an antenna body and a feed structure, the antenna body comprising a first bent branch and a second bent branch, a first end of the first bent branch being grounded and a second end being electrically connected to the second bent branch, and a gap between the first bent branch and a ground end causing the antenna assembly to have a slot mode, which reduces the size of the first bent branch. The bending direction of the first bent branch is opposite to the bending direction of the second bent branch. The second bent branch causes the antenna assembly to have a monopole mode, which increases the operating modes of the antenna assembly, thereby increasing the applicable range of the antenna assembly. The first bent branch and the second bent branch form two resonance structures, i.e., the antenna assembly can transmit signals of two frequencies, thereby increa
