Abstract: An information terminal of the present invention is provided with a card. The information terminal includes a main body provided with an antenna. When the card is inserted into a recessed portion formed in the main body, a first electrical circuit of the card is electrically connected to the information terminal and a conductor in the card is electrically coupled to the antenna. Accordingly, the card can be miniaturized.

Abstract: In a high-frequency module, a setting pattern formed on a circuit board has band-shaped first and second grounding lands, and first and second lands. External conductors of first and second forms of coaxial connectors are solderable to the grounding lands, and central conductors of first and second forms of coaxial connectors are solderable to the first and second lands. Accordingly, the first and second forms of coaxial connectors can be mounted on one circuit board. The circuit board can be manufactured more easily and at a lower cost in comparison with conventional art.

Abstract: A chip-type antenna and a snaked, band-shaped conductor as a pair of radiation elements fed at the center, a circuit unit having a transmission/reception circuit that is connected to respective feeder lines for the radiation elements, and a connector that connects, to an external circuit, lead lines leading from the circuit unit are arranged on an insulative substrate to be mounted on a mother board. The pair of radiation elements extend along two adjoining sides of the insulative substrate so as to generally assume an L-shape in a plan view.

Abstract: In the transmission/reception unit according to the present invention, a first corner of a cover, which is located in the vicinity of transmission and reception terminals and a ground terminal of an antenna, or the vicinity of the corner, is soldered to a non-ground wiring pattern and an electrical length of the ground conductor from the ground terminal is increased. This ensures that even in a compact transmission/reception unit, the electrical length is equivalent to &lgr;/4 and the antenna gain is improved; therefore, a transmission/reception unit with a satisfactory transmission/reception sensitivity can be realized.
