An antenna cable noise suppression structure includes a plurality of antenna cables and a noise suppression member that has electrical conductivity and is electrically connected to each of outer conductors of two or more antenna cables. Further, the noise suppression member is electrically connected to an outer conductor of each antenna cable at a position at which a distance from an end of each antenna cable is equal to or less than one quarter of a wavelength calculated based on a frequency of a signal transmitted by each antenna cable. Further, the noise suppression member and the outer conductor that is electrically connected to the noise suppression member are grounded to a grounded portion.

A thin antenna includes an antenna element, a first spacer, a second spacer, a first ground plane and a second ground plane. The antenna element is formed in a column shape, and has a top surface and a bottom surface facing each other. The first and second spacers are made of an insulating material. The first ground plane is formed larger than the top surface of the antenna element. The second ground plane is formed larger than the bottom surface of the antenna element. The first ground plane is disposed to face the top surface of the antenna element via the first spacer. The second ground plane is disposed to face the bottom surface of the antenna element via the second spacer. A power is fed at one of the top surface and the bottom surface of the antenna element.

Thin antenna

A folded antenna includes: a substrate including a dielectric base material and a ground disposed on a first surface of the dielectric base material; and an antenna element including a bent portion bent in a direction perpendicular to the substrate, and a folded portion further bent in a direction parallel to the substrate from the bent portion and capacitively coupled to the ground via the dielectric base material. An impedance of the folded antenna is adjusted by adjusting an area of the folded portion by changing a width dimension of the folded portion without changing a height dimension of the bent portion.

Folded antenna

A slot antenna is provided with a metal cylindrical antenna element. The antenna element is formed at a height of &#x3bb;/4 or less when &#x3bb; is a wavelength of an antenna frequency to be used. Further, the antenna element has a slot for vertical polarization having a length of &#x3bb;/2 or more in a circumferential direction.

Slot antenna

A connector is provided, which can seek miniaturization by suppressing external form dimensions of an inner housing. The connector includes, as means for engaging and uniting housing division bodiesandthat constitute the inner housing, engagement piecesequipped on one side of the housing division bodies and inserted between adjacent terminal accommodation portionsin the other side of the housing division bodies, and locking portions equipped between the terminal accommodation portionsin the other side of the housing division bodies and engaged with the inserted engagement pieces to make the housing division bodiesandin a connection state.

Miniaturization connector assembly

An object is to provide a board-mounted connector which has an assembly fitting opening provided on the attachment surface side of an external shield shell onto a circuit board such that a housing assembly can be fit from the assembly fitting opening into the external shield shell, and is capable of improving the ease of assembling the housing assembly. In a board-mounted connectorA, a housing assemblyA to be fit from an assembly fitting openingprovided at an external shield shellA into the external shield shellA is made by integrally forming an internal housingthat accommodates a plurality of connection terminal membersand an external housingthat covers the outer circumference of the internal housingand accommodates and holds the internal shield shell

Board-mounted connector

A circuit board mounted connector includes an exterior shield shell and a housing assembly. The exterior shield shell has a first face to be mounted on a circuit board to define an electromagnetic shielding space and a second face which is orthogonal to the first face and is opened for installation of a mating connector. The housing assembly is fitted in the exterior shield shell so that the mating connector is connected thereto. The housing assembly includes a connecting terminal member, an interior housing, an interior shield shell, and an exterior housing. The exterior shield shell includes an assembly mounting opening through which the housing assembly is installed into the exterior shield shell, in the first face of the exterior shield shell.
