To attain more comfortable mobile communication than that by a conventional antenna by realizing an antenna with a high antenna gain regardless of its compactness and to realize an excellent communication environment even in a small space of a base station.

A coil conductor is used for one antenna element 1 and a conductor inserted through the loop conductor 1 is used for another antenna element 2. Then a feeding point 5 is provided between a winding start 3 of the coil conductor and a midpoint of the antenna element 2 inserted through the loop Thus, even in the case of an antenna formed compact as a lumped constant circuit, the antenna with a small loss is small, that is, with a high antenna gain and a broad available band width is realized.
