摘要： In an antenna structure including a feeding radiation electrode and a non-feeding radiation electrode that are electromagnetically coupled to each other, due to formation of a main slit, the feeding radiation electrode includes a U-turn portion in the middle of a path circumventing the main slit from a feeding end to an open end. A sub-slit for forming an open stub that is connected to the U-turn portion and that provides the U-turn portion with electrostatic capacitance is formed in the feeding radiation electrode. By changing a value of the electrostatic capacitance to be provided by the open stub to the U-turn portion of the feeding radiation electrode, variable control of a higher-order resonant frequency F2 of the feeding radiation electrode 2 can be achieved while suppressing fluctuations in a resonant state (for example, a fundamental resonant frequency F1 and a Q-value) of a fundamental resonant frequency band of the feeding radiation electrode, in an electromagnetic coupling state between the feeding radiation electrode and the non-feeding radiation electrode, and in an impedance matching state.

摘要： An antenna structure includes a surface-mounted antenna which has a base member. A radiating electrode and an antenna-side control electrode are disposed on the base member. A capacitance is generated between the antenna-side control electrode and an open end of the radiating electrode, and the antenna-side control electrode electrically floats. A board-side control electrode which is electrically connected with the antenna-side control electrode and which electrically floats is disposed on a mounting board. The board-side control electrode is connected with a ground conductor at high frequencies through a resonant frequency adjuster. The resonant frequency adjuster has a capacitance or an inductance. By changing the capacitance or the inductance, the resonant frequency of the radiating electrode can be changed without changing the surface-mounted antenna.

摘要： The anode member for a solid electrolytic capacitor according to the present invention comprises an anode body made of a valve metal foil having a purity of not less than 99 wt %, and an anode layer formed on the anode body and made of a sintered body of a valve metal powder. By limiting the amount of impurity contained in the valve metal foil to an amount of not more than 1 wt %, impurities in a dielectric oxide film formed by anodic oxidation, namely defects in the dielectric oxide film can be suppressed, so that the resultant solid electrolytic capacitor can have its leakage current lowered with its ESR (equivalent series resistance) being kept low, and that the electrolytic capacitor can be made to have a smaller size and a higher capacitance. The present invention also provides an electrolytic capacitor having a low leakage current, a low ESR, a small size and a high capacitance by using the above novel anode member as well as a method of making the same.

摘要： An antenna apparatus has improved gain, and its characteristics are barely affected by changes in the external environment in which it used, such as when it is placed close to a ground conductor. A surface-mount antenna and a monopole antenna are fed by a single feeding point, and the direction of an open end of the surface-mount antenna, taking a ground end of a radiation electrode as a reference, runs opposite to the direction of the open end of the monopole antenna, taking the feeding terminal as a reference.

摘要： A chip-type solid electrolytic capacitor includes a cathode conductive layer provided on a whole surface of a cathode layer formed on an outer surface of a capacitor element, which whole surface is opposite to a surface where an anode lead wire is lead out, and on a surface adjacent to the first-mentioned whole surface. With this arrangement, if the capacitor element is obliquely inserted into a mold during the formation of a resin shell, the inner walls of the mold will not come into contact with cathode layer of the capacitor element, but will instead come into contact with the cathode conductive layer to prevent the cathode layer from being exposed to the resin shell. As a result, any possible damage to the cathode layer of the capacitor element when the peripheral surface of the resin shell on a cathode side is subjected to roughening is prevented to eliminate defects in electric characteristics such as leakage of electric current and a tan.delta. value.
