BASE STATION ANTENNA STRUCTURE HAVING MULTI-BAND DIPOLE ELEMENT ARRAY

摘要

PURPOSE: A base station antenna having a multi-band dipole element array is provided to effectively cope with increased traffic of a specific region by performing a beam tilting function. CONSTITUTION: A base plate(100) provides a reflective surface reflecting transmitting/receiving electric waves. A first dipole element(110) is installed in the base plate and provides a radiation function of a first band. A second dipole element(120) is located between the base plate and the first dipole element and provides a radiation function of a second band with a higher frequency than the first dipole element.
