摘要： First and second radiating conductors are concentrically formed on a top surface of a dielectric substrate, and a grounding conductor is formed on a bottom surface of the dielectric substrate. A feeding pin is connected to a power feeding point of the first radiating conductor. Shorting pins are connected to an inner circumferential portion of the second radiating conductor to be shorted by the grounding conductor. An interval between the radiating conductors allows the first and second radiating conductors to be electromagnetically coupled with each other. When the first radiating conductor is excited at a frequency fH by direct feeding from the feeding pin, the second radiating conductor is fed by the coupling, so that it is excited at a frequency fL lower than the frequency fH.

摘要： A patch antenna includes a dielectric substrate having a through-hole, a patch electrode on the dielectric substrate, and a feed pin inserted in the through-hole. A head of the feed pin is soldered to the patch electrode. The bottom surface of the head of the feed pin has projections for generating a clearance between the bottom surface of the head and the opposing surface of the patch electrode, which is filled with a solder. The solder can function as a cushion that prevents a thermal contraction or a thermal expansion of the head of the feed pin to directly affect the dielectric substrate.

摘要： An antenna device includes a ground conductor plate, and a radiating conductor plate made of a metal plate, which is spaced from the ground conductor plate. The radiating conductor plate is provided with adjusting means for adjusting the electrical length. Thus, the correction of the electrical lengths can be made even if there is a difference between the electrical lengths of the radiating conductor plate caused by assembling errors, etc. In addition, when the antenna device is used in a state in which it is connected to external equipment, the adjusting means allows the adjustment of the electrical lengths of the radiating conductor plate even if the electrical lengths of the radiating conductor plate are subjected to the electrical influence from the electrical equipment and its surrounding environment.
