摘要： The present invention relates to a power divider and a power combiner employing dual band-Composite Right/Left-Handed (CRLH) transmission lines. A power divider including an input terminal and two output terminals according to the present invention includes two transmission lines each having two terminals connected to the input terminal and the output terminals, respectively, and two short-stubs having one terminals connected to the output terminals, respectively, and the other terminals connected to grounds. The transmission line may employ a first dual band-CRLH transmission line having a double value of a termination impedance, which is substantially connected to the output terminal, as a characteristic impedance, and the short-stub may employ a second dual band-CRLH transmission line, which has substantially the same value as that of the termination impedance as a characteristic impedance. The first dual band-CRLH transmission line and the second dual band-CRLH transmission line generate phase delay of 90 degrees in a high frequency band and phase delay of -90 degrees in a low frequency band with respect to an input signal.

摘要： There is herein disclosed a miniature antenna with an adjustable resonant frequency without any change of the radiation performance, and an apparatus including the same. The antenna comprises two radiation conductors connected to a feed section and a ground plane, respectively, and a resonant circuit section as a zero-order resonator including inductors, transmission lines and a capacitor. The inductors and/or capacitor are configured of a variable element so that the impedance of the variable element can be controlled to adjust the resonant frequency of the antenna. In addition, the installation position and the size of the ground plane within the apparatus with respect to the transmission lines can also be controlled to adjust the resonant frequency of the antenna. Alternatively, the antenna may further comprise a variable capacitor connected to the inductors so as to adjust the effective inductance and change the resonant frequency. The radiation lines of the antenna are not related with determination of the resonant frequency, and thus the radiation performance is not affected by the adjustment of the resonant frequency.

The control apparatus for a brushless direct current hub motor includes an input unit generating a forward/reverse RPM control command of the motor, a sensor unit detecting rotation of the motor, a controller outputting a motor driving signal by combining a motor rotational signal of the sensor unit with the RPM control command of the input unit, a switching device unit supplying a driving current to the motor by performing switching operation in accordance with the combined signal, and a brushless direct current hub motor rotating by the driving current. The brushless direction current hub motor has a multi-phase independent parallel winding. The controller drives the switching device unit such that a switching-on time of a lower end signal of the H-bridge is longer than a switching-on time of an upper end signal of the H-bridge to eliminate residence power of a motor coil. An apparatus/method is provided. The residence current of the motor coil can be eliminated and thus hysteresis phenomenon can be prevented.
