PROBLEM TO BE SOLVED: To easily obtain a desired characteristic even in the case that a specific dielectric constant or a specific permeability of a board is in dispersion and in the case that a size of electrode patterns formed on the board is in dispersion and to easily manufacture the surface mount antenna with a different characteristic by using a mother board on which electrodes have already been formed in common. SOLUTION: First electrodes 1 extended linearly are formed on a mother board 11, 2nd and 3rd electrodes 2, 3 having respectively a prescribed length in parallel with the 1st electrodes 1 are formed at an interval of A so as to divide lines respectively orthogonal to the 1st, 2nd and 3rd electrodes and 4th electrodes interconnecting the ends of the 1st and 2nd electrodes are formed to an end face of the dielectric board after line division. The length of the electrodes acting like radiation electrodes is decided depending on the position of division lines when the dielectric board is cut from the dielectric mother board 11 so as to decide a resonance frequency of the surface mount antenna. |
