Document Type and Number:
WIPO Patent Application WO/2012/153758
Kind Code:
A1
Abstract:
[Problem] To provide an antenna that can transmit/receive electromagnetic waves in a wide band of frequencies, can obtain a high gain, and can freely perform fine adjustments on the height of the used frequency band. [Solution] The antenna (10A) is provided with an unbalanced feeder member (11), a dielectric substrate (12), a resonance conductor (13), a ground conductor (14), and a feed element (15). The resonance conductor (13) is formed from a first and second resonance conductor section (24a, 24b) that extend forward in the axial direction of the unbalanced feeder member (11) in parallel to an electricity supply section (21). The ground conductor (14) is formed from: an affixed section (30) electrically connected to the unbalanced feeder member (11); and a first and second ground conductor section (31a, 31b) that extend backwards in the axial direction of the unbalanced feeder member (11) in parallel to a non-electricity-supply section (22). In the antenna (10A), the first and second resonance conductor sections (24a, 24b), the feed element (15), the affixed section (30), and the first and second ground conductor sections (31a, 31b) are joined to one surface (16) of the substrate (12).
