Abstract: To prevent both increase in impedance and a short circuit, a connector cable is configured such that a connector and a shielded cable are connected via a relay substrate. The shielded cable includes at least an inner conductor, a dielectric covering the inner conductor, and a shield member covering the dielectric. The inner conductor is connected to a contact of the connector at a part where the shield member and the dielectric are removed to expose the inner conductor. At least directly under a part where the shield member is removed to expose the dielectric, a ground (GND) conductor layer on a front surface of the relay substrate is arranged. The GND conductor layer on the front surface of the relay substrate, which is arranged directly under the part where the shield member is removed, is covered with an insulating member.

Abstract: A connector comprises a housing, a terminal and a shell. The terminal has a held portion held by the housing, a first portion extending rearward from the held portion and a second portion extending forward from the held portion. The first portion has a connectable portion configured to be connected to a first object. The second portion has a resiliently deformable support portion and a contact portion supported by the support portion. The contact portion is pressed against a second object when the connector is fixed on the second object. The shell has a first upper plate and a second upper plate which is located below the first upper plate. The first upper plate covers the first portion of the terminal from above. The second upper plate covers the second portion of the terminal from above.

Abstract: An antenna element comprises an upper conductor, first lower conductors, second lower conductors, first leg portions, second leg portions and feeding portions. The upper conductor has a middle portion, a ring portion and coupling portions. The ring portion continuously surrounds the middle portion, and the coupling portions couple the middle portion and the ring portion to each other. The first leg portions extend from the middle portion, and the second leg portions extend from the ring portion. The first lower conductors and the second lower conductors are distinct and separated from one another and are apart from the upper conductor in an up-down direction. The first lower conductors are connected to the first leg portions, and the second lower conductors are connected to the second leg portions. The feeding portions extend from the upper conductor.
