Abstract:
PROBLEM TO BE SOLVED: To provide an antenna which makes a base part of a helical antenna electromagnetically approximate a transmission line feed on a surface of a substrate and includes a three-dimensional shape section of a flex circuit. SOLUTION: The present invention relates to a helical antenna including a section of a microstrip of an antenna feed segment on a surface of a substrate, a generally cylindrical support core that conforms with the shape of the helical antenna and is held at a predetermined position on the substrate, and a conductor of a flex circuit in a comparatively thin ribbon shape of dielectric coating. The conductor includes a first segment of the conductor fixed by being adhesively wound around an outer surface of the core in order to form a decal-like helical antenna winding wire on the core, and a second segment of the conductor fixed generally in a lower area of a plane in a base part of the core at a position of the conductor for electromagnetic coupling in proximity with a portion of microstrip feed at a predetermined position on the substrate.

PROBLEM TO BE SOLVED: To provide a small-sized and lightweight helical antenna having a large gain, and to provide a helical antenna array. SOLUTION: A dielectric cylindrical body 1 with a helix conductor 2 is provided at a conductive flat plate 3. A strip-shaped conductive plate 5 is provided, between a lower edge of the helix conductor 2 and a power feed point at a prescribed position of the conductive flat plate 3. Then, the impedance between input impedance of the helix conductor and the power feeding device is matched. Upper and lower conductive plates 3 and 10 form a parallel flat waveguide. A probe, projecting into the parallel flat waveguide, is mounted on the side of lower conductive flat plate 10, and the lower edge of the strip conductive plate 5 is connected to the edge of the probe.
