<p>In the present invention, ground conductors (11, 11F) are formed on a first surface of a substrate (10), and a ground conductor (12) is formed on a second surface of the substrate (10). A ground conductor non-forming region (8) is provided along a first side (S1), which is a part of the outer edge of the ground conductor (11). A series circuit is connected to both ends of the ground conductor non-forming region (8) in a direction along the first side (S1), the series circuit contains emission electrodes (13, 14), capacitance elements (C1, C2), and the ground conductor (11F). As an example, the emission electrodes (13) are emission electrodes for a 5 GHz band, and the emission electrodes (14) are emission electrodes for a 2.4 GHz band. The capacitance element (C1) creates a gap capacitance between the emission electrode (13) and the emission electrode (13), and the capacitance element (C2) creates a gap capacitance between the emission electrode (14) and the emission electrode (14).</p> |
