A mobile communication base station antenna includes: a reflecting plate; a first patch-type radiating element installed on the reflecting plate; a second dipole-type radiating element installed and stacked on the first radiating element; and a circuit board for feeding power installed on the same surface as a surface of the reflecting plate on which the first radiating element and the second radiating element are installed and having a conductive pattern formed thereon to provide a feeding signal to the first radiating element.

Mobile communication base station antenna

The present invention relates to a multiband antenna comprising: a reflector providing a ground plane; a first radiation module for a first frequency band, provided on the reflector; and a plurality of second radiation modules for a second frequency band, laminated on the first radiation module, wherein: the first radiation module includes first to fourth radiation elements symmetrically combined in four directions on an entire plane, wherein each of the first to fourth radiation elements includes a radiation arm in a cup shape and a support for supporting and fixing the radiation arm to the reflector, and the second radiation modules are provided to each radiation arm of the first to fourth radiation elements, wherein the lower surface of the cup shape of each radiation arm of the first to fourth radiation elements is designed to have a predetermined area for providing the ground plane to the second radiation modules.

Antenna radiation element and multiband antenna

The present invention relates to a multi-band, multi-polarized wireless communication antenna, which comprises: a reflector; at least one first radiation module of a first band which is installed on the reflector; and at least one second or third radiation module of a second band or a third band installed on the reflector, wherein the first radiation module comprises first to fourth radiating elements having a dipole structure, the first to fourth radiating elements are configured such that every two radiating arms thereof are connected in the shape of letter '&#xac;', one of the two radiating arms is configured to be placed side by side along side of the reflector, and the second or third radiation module is installed to be included within an installation range of the first radiation module.
