PURPOSE:To effectively utilize the space in the dielectric cover with a wide band by cladding other conductor plates in the inner face of the dielectric cover. CONSTITUTION:The conductor plate 7 is clad to the inner face of the dielectric cover 5. In feeding power to the conductor plate 7 through the space coupling, the resonance frequency characteristic in the presence of the conductor plate is superimposed on the resonance frequency of the antenna system in the absence of the conductor plate, the height of the conductor plate is increased equivalently and the broad band of input impedance is realized.
