摘要： Disclosed is a TEM mode resonator having as a means for adjusting the resonance frequency a simple frequency adjusting mechanism appropriate for size reduction while permitting easy mounting of a varactor diode for varying the resonance frequency thereto. Below a strip transmission line 2 is provided a slot 7 having a length L perpendicular to the transmission line as located at an outer ground conductor surface 3 of a one-fourth wavelength type microstrip line resonator having its one end short-circuited. According as increasing the slot length L, the resonance frequency of the resonator reduces, which characteristic is utilized as a means for adjusting the resonance frequency. By connecting a varactor diode at a center portion of the slot line and varying the voltage applied to the diode, the resonance frequency can be varied.

Another ladder filter includes the second piezoelectric resonator as the series resonator to decrease a capacitance between the electrodes to increase an amount of attenuation.

摘要： A temperature-stabilized MIC solid state oscillator in the form of a planar transmission circuit has two strip line resonators respectively having chip capacitors inserted serially in the middle of the strip lines. Both of the chip capacitors have linear capacitance temperature characteristics. One strip line resonator operates as a band rejection filter and as a load circuit of an oscillating device. The other strip line resonator operates as a serial resonator to ground a port of the oscillating device that should be grounded. The oscillating frequency characteristics versus temperature are compensated in an excellent manner due to the provision of the two strip line resonators.

摘要： A small-sized antenna device is used for portable telephone equipment and is capable of preventing the receiving strength from being degraded due to a change in the application environment as well as the mounting thereof onto a small radio equipment case. The antenna device has a linear antenna for producing an electric current flux and a coil-shaped antenna for producing a magnetic current flux including a plurality of half-wavelength helical coils connected in series so as to have two adjacent coils coiled in opposite directions with respect to each other, and carries out polarization diversity. Degradation in the characteristics of both antennas due to differences in operational principle can be prevented from taking place simultaneously, resulting in realizing a good reception of a radiowave. In addition, the antenna axes of both antennas can be disposed in parallel and close to each other, thus miniaturizing the device itself.
