摘要： A radio terminal device has an antenna element, a coil, a switch, an RF circuit section and a conductive substrate. The switch is used to switch between a case where current distribution exists only in the antenna element and its vicinities and a case where the current distribution exists not only in the antenna element and its vicinities but also in other places. Additionally, the switch is switched in accordance with the usage pattern in which the user uses the radio terminal device (e.g., telephone call and data communication). This allows the transmission/reception to be performed with the antenna polarization and directivity suitable for the usage pattern. Thus, there can be provided a radio terminal device that exhibits a reception characteristic suitable for a respective situation.

摘要： In an antenna unit adapted to be incorporated inside a main body of a mobile radio set, there are provided a pair of helical antenna elements (102), (103) connected to a balanced feeding line (104), the helical antenna elements having antenna axes in a direction parallel to a base plate (201) of the radio set, and being arranged in proximity to the base plate of the radio set at a sufficiently small distance as compared with their wavelength. By conducting a balanced power supply to the helical antenna elements, an electric current component flowing on the base plate of the radio set can be reduced, thus decreasing influence of the human body when the radio set is carried by the human hand. Additionally, the antenna can posses radiation characteristics of both the electric current type antenna and the magnetic current type antenna, and therefore, the receiving performance when the radio set is tiltedly used will be enhanced.
