<p>PROBLEM TO BE SOLVED: To attain miniaturization without using a dielectric substrate with a high dielectric constant, and to attain low frequencies without large-scaling a dielectric substrate by realizing the pattern of a radiation electrode going from a first main surface through an edge face to a second main surface back and forth. SOLUTION: In a dielectric substrate 11, electrodes 1c, 2c, 3c, and 1g are formed on an upper surface (a first main surface), electrodes 1a, 2a, 3a, and 1e are formed on a lower surface (a second main surface), electrode 1b, 2b, and 3b are formed on a front left edge face, and electrodes 1d and 1f are formed on a back right edge face. The electrodes 1a, 1b, 1c, 1d, 1e, 1f, and 1g are continuously formed in this order so that a radiation electrode 1 can be formed. Also, the electrodes 2a, 2b, and 2c are continuously formed in this order so that a power feeding electrode 2 can be constituted. Moreover, the electrodes 3a, 3b, and 3c are continuously formed in this order so that a ground electrode 3 can be constituted. The radiation electrode 1 is constituted so as to be folded from the upper surface through the back right edge face of the dielectric substrate 11 to the lower surface so that the length of the radiation electrode 1 can be made longer.</p> |
