Antenna apparatus

A base station, comprising an antenna apparatus, wherein the antenna apparatus includes:

• an antenna component that is arranged on a passive side of the antenna apparatus and comprises a combiner, a phase shifter and, a splitter network;
• a radio frequency unit that is arranged on an active side of the antenna apparatus, formed by at least one independent radio frequency module, and connected to the antenna component to form an active antenna, wherein each radio frequency module comprises a radio frequency plate and a duplexer module;
• and
• a common unit that is arranged on the active side of the antenna apparatus and connected to the radio frequency unit;
• wherein the independent radio frequency module is a radio frequency module that supports independent field installation, maintenance, or replacement.
