<P>PROBLEM TO BE SOLVED: To provide a technology that does not deteriorate an antenna characteristic even if a base station antenna for mobile communication is formed with the use of a plurality of array antennas. <P>SOLUTION: A base station antenna for mobile communication 30 comprises two array antennas 31a and 31b which are arranged side-by-side in a horizontal direction. Antenna elements 35 of an array antenna 31 are divided into first to third groups G1-G3. A first feeding port 37-1 is connected to the antenna elements 35a in odd numbered groups (the first group G1 and the third group G3) of the array antenna 31a which is one of the array antennas, and the antenna element 35b in an even numbered group (the second group G2) of the array antenna 31b which is the other of the array antennas. A second feeding port 37-2 is connected to the antenna element 35a in the even numbered group (the second group G2) of the array antenna 31a which is one of the array antennas, and the antenna elements 35b in the odd numbered groups (the first group G1 and the third group G3) of the array antenna 31b which is the other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
