Abstract: An antenna assembly includes a first interface for receiving a first RF signal, a second interface for receiving a second RF signal, and an antenna array including a first array and a second array that extend vertically. The first array includes a first radiating element and a second radiating element, and the second array includes a third radiating element and a fourth radiating element. A power coupling circuit is provided, which is configured to feed a first sub-component of the first RF signal and a first sub-component of the second RF signal to the first radiating element and/or the third radiating element in a power-reduced coupling manner. A plurality of radiating elements in the first array are electrically connected to the first interface, and a plurality of radiating elements in the second array are electrically connected to the second interface, respectively.
