<P>PROBLEM TO BE SOLVED: To provide an antenna facilitating installation to a surface of an existing facility and having power radiation distribution being omnidirectional in crossing two polarizations. <P>SOLUTION: An antenna made of a planar conductor includes a ground unit, a first antenna element, a feeding point formed between the ground unit and the first antenna element, and second and third antenna elements which are connected to the first antenna element via a connection unit and formed so as to be branched from the connection unit into two portions. The antenna has power radiation distribution characteristics being omnidirectional in crossing two polarizations. <P>COPYRIGHT: (C)2013,JPO&INPIT |
