Transverse electromagnetic mode resonator |
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.
