Abstract: PROBLEM TO BE SOLVED: To provide a small-sized and high-performance mechanical vibration filter adapted to a high frequency band.
SOLUTION: The mechanical vibrator is made up of a microcylindrical beam 5 to increase the mechanical resonance frequency, and the microcylindrical beams 5 are arranged in an array. Common sensing electrodes 6 are disposed around the microcylindrical beams 5 at predetermined intervals to suppress a fault of an output signal. The vibration of a part of the mechanical vibrators is constricted to enable the observation and removal of the noise component accompanying the direct electromagnetic coupling from the input signal to the output signal.

Abstract: PROBLEM TO BE SOLVED: To provide a high-performance high-frequency filter that has little passage loss in an area of more than cutoff frequency.
SOLUTION: The present filter is one to be inserted midway in the high-frequency transmission line using signal wires 12L and 12R provided on the surface of a substrate 11. In order to form this filter, a geometric structure in which capacitive elements C
1 and C
2 and non-capacitive element R are connected in parallel in a signal propagation direction of the high-frequency transmission line runs through the center line of the signal wires 12L and 12R in a plane vertical to the signal propagation direction and symmetrical with respect to the direction at right angles to the substrate 11. The capacitive elements C
1 and C
2 and the non-capacitive element R are arranged in a parallel direction on the surface of the substrate 11. Moreover, the non-capacitive element R is arranged in between with the two capacitive elements C
1 and C
2 symmetrical to each other on the outer side. Since the concentration of a current on the edge of the filter can be avoided, there is little passage loss.

Abstract: PROBLEM TO BE SOLVED: To construct a resonator in which an electromagnetic field in the opening of an electrode is shielded and a conductor loss is also reduced by suppressing current concentration, a filer, an oscillator, a duplexer and communication equipment in which they are used. SOLUTION: Electrode patterns 2' dividing a slot width are formed in the vicinity of the short circuit position of a slot 3. Thus, an electromagnetic field is better shielded and a conductor loss is also reduced.

Abstract: PURPOSE:To enhance the RF/DC conversion efficiency by selecting a distance from a rectifier means till a harmonic interruption means to be nearly an odd number of multiple of a 1/4 wavelength at the cut-off frequency. CONSTITUTION:The rectenna is provided with an input terminal TIN an input filter section FIN, a rectifier means 1, an output filter section FOUT, an output terminal TOUT, and open stubs 111-117 to interrupt 2nd-5th harmonics. Then a distance (line length) between the rectifier means 1 and the open stub to interrupt an n-th harmonic is selected to be an odd number of multiple of a 1/4 wavelength lambdag of the n-th harmonic. The open stub 131 whose length is 1/4 wavelength of a fundamental wave is short-circuited with respect to the fundamental wave whose fundamental frequency is f0 and open to its DC component. The open stub 133 whose length is 1/8 wavelength of the fundamental wave is short-circuited with respect to the 2nd harmonic wave whose frequency is 2f0, and the open stub 135 whose length is 1/16 wavelength of the fundamental wave is short-circuited with respect to the 4th harmonic wave whose frequency is 4f0. As a result, not only the fundamental wave but also its harmonic components are power-converted.
