A flexible printed board electrically connected to an electronic component (for example, a liquid crystal panel) by thermal compression bonding, including a flexible substrate, a terminal portion formed on one surface of the flexible substrate and having a plurality of connection terminals to be connected to the electronic component, a wire portion having a plurality of wires formed on the other surface of the flexible substrate, and a plurality of through wires formed inside through holes penetrating the flexible substrate in a compression bonding connection area to the electronic component of the terminal portion to connect the connection terminals of the terminal portion and the respective wires of the wire portion.

Flexible printed board

An antenna () of the present invention includes: a dielectric substrate (); an antenna conductor () including: a power feeding line () that extends in a first direction; and a stub (); and a ground conductor (). The antenna () further includes: a first parasitic element () facing a first side of the stub () which first side is on a side of a direction opposite to the first direction; and a second parasitic element () facing a second side of the stub () which second side is on the first direction side.

Microstrip antenna

An antenna includes a dielectric substrate, an antenna conductor, a ground conductor, a waveguide tube, a shield, and short-circuit portions. The shield is provided with a cut having a reverse-taper shape whose width becomes greater from an open end of the cut to an inward end of the cut. The short-circuit portions are provided along a whole periphery of the shield except for a portion provided with the cut.
