Abstract
A base station antenna includes a feed network, a cable and an adapter structure. The feed network includes a cavity, and an internal structure in the cavity. The adapter structure includes a first transmission line. A first end of the first transmission line is electrically connected to the internal structure. A second end of the first transmission is electrically connected to the cable. The first transmission line is configured to transmit a radio frequency signal. The first transmission line is at least partially located outside the cavity.
