An antenna and a detecting device are provided. The antenna includes a ground plane, a pole and a microstrip line. The detecting device includes an oscilloscope and the antenna that is connected with the oscilloscope.

An antenna device and a beam direction adjustment method are provided. The antenna device includes an antenna element, a metal element, and a substrate. The antenna element and the metal element are separately disposed on the substrate at a preset distance. A ground point of the metal element is fastened on a pad of the substrate, and the ground point is on a side of the metal element close to the antenna element. A first reverse current opposite to an antenna current generated by the antenna element is obtained through coupling on the side of the metal element close to the antenna element, and a second reverse current opposite to a substrate current generated by the substrate is obtained through coupling at a lower part of the metal element that is in contact with the substrate.

The present invention addresses the problem of providing an installation body that, irrespective of the relative angle between a transmitter and a receiver, enables reduction in size and thickness of the transmitter and simultaneously enables improving of the probability of being able to achieve better reception of radio waves transmitted by the transmitter. In order to solve this problem, the installation body according to the present invention is provided with a conductor that is located in the vicinity of an antenna of the transmitter, in a state in which the transmitter is disposed in proximity to the installation body. The conductor is configured such that an induction current is generated therein by a drive current of the antenna. The induction current has a current component in a direction different from the direction of the drive current.

A vehicle includes: a roof panel; an antenna disposed on an edge portion of one side the roof panel; and a vector transformer extending from the edge portion of one side of the roof panel to an outside of the roof panel. A surface area of the vector transformer may be smaller than that of the roof panel.

An antenna directivity control system includes an antenna including a plurality of antenna elements, feeding points for the plurality of antenna elements being mutually different; and a controller for controlling weight for each of the plurality of antenna elements, wherein each of the plurality of antenna elements includes a feed element connected to the feed point, and a radiating element that functions, upon power being fed by establishing electromagnetic field coupling with the feed element, as a radiating conductor, and wherein the controller controls a directivity of the antenna by adjusting an amplitude of a signal at each of the feeding points.

An antenna structure includes a metallic frame and a stub antenna. The metallic frame defines a slot and two gaps. The two gaps are positioned at two ends of the slot and are substantially perpendicular to the slot. The metallic frame is divided into a first portion and a second portion by the slot and the two gaps. A portion of the metallic frame surrounded by the slot and the two gaps forms the first portion. The first portion serves as a radiator of the antenna structure and is grounded through the second portion. The stub antenna is positioned at an interior of the metallic frame and is spaced from the radiator.
