    • A wireless terminal management apparatus includes a communication unit performing short-distance wireless communication with wireless terminals; a registering unit that registers information indicating a wireless terminal connectable to the communication unit; a determining unit that determines whether the number of registrations of information indicating a wireless terminal registered in the registering unit has reached a given number of wireless terminals allowed to connect to the communication unit; an updating unit that when a non-registered wireless terminal is nearby and if the number of registrations has reached the given number, updates the number of registrations such that information indicating the non-registered wireless terminal becomes registered; and a searching unit that searches for a wireless terminal nearby, where if a search result indicates no registered wireless terminals and a non-registered wireless terminal nearby, the updating unit updates to enable information indicating the non-registered wireless terminal to be registered by the registering unit.

    • An object of the invention is to provide a communication terminal capable of keeping the reception sensitivity good if the communication terminal is placed on a metal plate with the communication terminal laid on its side without the need for changing the size or the design of the main body of the communication terminal. A board (125) to which an antenna (107) is connected is provided inside a lower casing (105). The board (125) is provided with a GND plane to which a radiating element (121) is connected. An auxiliary bottom board (123) is joined to the radiating element (121) in a roughly perpendicular direction thereto. The radiating element (121) and the auxiliary bottom board (123) are conductors. A high-frequency current (131) flows into the board (125). Since a high-frequency current (133) of an opposite phase flows through a metal plate (141) because of the mirror image effect in a state in which the communication terminal is placed on the metal plate (141), the high-frequency current (131) is canceled and the radiation of the antenna (107) is weakened. However, the components perpendicular to the metal plate (141) do not cancel each other because of the mirror image effect and thus the radiating element (121) forms a dipole antenna symmetrically with the metal plate (141).
    • 本发明的目的是提供一种通信终端,如果通信终端被放置在金属板上,并且不需要改变主体的尺寸或设计,则能够保持接收灵敏度良好 的通信终端。 在下壳体(105)的内部设置有与天线(107)连接的电路板(125)。 板(125)设置有连接辐射元件(121)的GND平面。 辅助底板(123)与辐射元件(121)大致垂直的方向连接。 辐射元件(121)和辅助底板(123)是导体。 高频电流(131)流入电路板(125)。 由于由于在通信端子放置在金属板(141)上的状态下的镜像效应,相反相位的高频电流(133)流经金属板(141),所以高频电流 (131)被消除,并且天线(107)的辐射被削弱。 然而,由于镜像效应,垂直于金属板(141)的部件不会彼此抵消,因此辐射元件(121)与金属板(141)对称地形成偶极天线。
