Base station antenna device with built-in transmitting and receiving module

The present invention relates to a base station antenna device containing a transmission and reception module, including at least one antenna element configured to transmit and receive RF signals; the transmission and reception module configured to be connected to the antenna element and to form transmission and reception paths for the RF signals; a digital control module configured to digitally control the RF signals transmitted and received by the antenna element by transmitting digital control signals to the transmission and reception module; and a power supply configured to supply operating power to the transmission and reception module and the digital control module. The present invention has the advantages of reducing power loss, decreasing signal noise and improving antenna characteristics because digital phase regulators and digital attenuators are provided in the transmission and reception module forming transmission and reception paths for RF signals so as to enable electronic beam control and because the transmission and reception module is integrated with and contained in the antenna element.
