A slot 2 is defined by notching a conductor plate 1, a first radiation conductor 3 and a second radiation conductor 4 are disposed by sandwiching the slot 2 as a boundary, a third radiation conductor 5 connected to either of the first radiation conductor 3 or the second radiation conductor 4 is provided in the slot 2, if necessary, on and after third radiation conductors, for example, a fourth and fifth radiation conductors connected to either of the first radiation conductor 3 or the second radiation conductor 4 are provided, a power is supplied in the slot by the use of conductor edges of at least two radiation conductors, if required, whereby two monopole antennas and slot antennas, which use respective electric currents on the first radiation conductor 3 and the second radiation conductor 4, are electrically formed, besides, antennas other than that described above are electrically formed by utilizing electric currents over on and after the third radiation conductors.
