Abstract:
    The invention includes radiant element plate, power divider, hard coaxial cable, and feeding ports. Two bottom ends of two pieces of power divider are connected to two feeding ports respectively. Being as double-sided board, the radiant element plate is composed of first dielectric plate, four antenna units, and ground plate. In same radiant element plate, antenna units are arranged in long direction. Interval between each two pieces of antenna units is equal. Each antenna unit is connected to hard coaxial cable. Two ends of inner conductor of the hard coaxial cable are connected to antenna unit on radiant element plate, and output port on the power divider respectively. Two ends of outer conductor of the hard coaxial cable are connected to ground plate of the radiant element plate, and ground plate of the power divider. Being in use for WLAN comm. system, the invention realizes omnidirectional/directional conversion of directional diagram with higher gain.
