PURPOSE:To simplify the construction and to make thin the antenna, by forming the power feeding line on the board with printing, and by unifying it with the microstrip board. CONSTITUTION:The silver foil disc 1 being the microstrip resonation radiator is formed on the dielectric substance board 2. Further, the board conductor 3 and the conductor ground plate 4 are conducted for normal operation of antenna, and the silver foil disc 1 and the board conductor 3 are shortened with the through-hole plating 7. The power feeding circuit consisting of the board conductor 12 of the first board, dielectric plate 13 of the first board, dielectric substance plate 14 of the second board, and board conductor 15 of the second board, is formed with the printing on the dielectric substance plate 2 and unified. Thus, since the radiation and power feeding sections are unified, the construction is simple, allowing to obtain very thin microstrip antenna. |
