摘要： In order to make a wireless handset smaller, a novel slot antenna is provided which can simplify the manufacture process and can be connected to a tunable circuit. A slot is disposed in a narrow side surface of a conductive cube, and a power supply conductor is arranged in the slot so as to intersect the slot. A variable impedance circuit is connected between conductors on opposite edges of the slot in a position at a constant distance from one of the ends of the slot. The control signal varies impedance of the variable impedance circuit so as to control the resonant frequency of the antenna. Transmit/receive antennas are connected by a support so as to align the directions of the main polarizations, and then are arranged on the circuit board of the wireless handset.

摘要： It is an object of the present invention to reduce the amount of spurious noise generated by an emission line spectrum of a signal propagating around the PLL of a PLL frequency synthesizer carrying out digital-signal processing.In order to achieve the object described above, the present invention provides a PLL frequency synthesizer with the following configuration.In a PLL frequency synthesizer having a charge-pump circuit, a waveform converter is provided at a stage behind the charge-pump circuit. The waveform converter converts the voltage waveform on a time axis of a rectangular wave output by the charge-pump circuit into a waveform which: is symmetrical with respect to a predetermined point of time; oscillates so as to have no direct-current component; and has a maximum value of the absolute values of maximums of wave heights thereof located at the center wherein the absolute value decreases uniformly as the wave height is separated farther away from the center. As a result, the amplitudes of a limited number of emission line spectra forming a spurious signal superposed on a signal propagating around the PLL can be made uniform and a maximum thereof can be held at a low value, allowing the direct-current component to be eliminated from the signal propagating around the PLL.
