Variable resonator and variable phase shifter
First Claim
1. A variable resonator which comprises a ground conductor, a dielectric, a signal conductor resonates to an electric signal at a particular high-frequency, and at least one switch, wherein:
- said signal conductor comprises one or a plurality of first conductor lines spaced apart by a predetermined distance from each other and a second conductor line connected with said one first conductor line or all of said first conductor lines;
said first conductor line or lines has or have a width different from that of said second conductor line whereby a signal path through which the high-frequency electric signal passes and which is longer than the line length of the second conductor line is defined;
one terminal or terminals of said switch or switches is or are connected with said first conductor line or lines while the other terminal or terminals of the switch or switches is or are connected with said second conductor line, or, alternatively both terminals of said switch or switches being connected with a plurality of said first conductor lines, whereby selectively opening and closing said switch or switches will electrically disconnect and connect between the corresponding conductor lines with which the both terminals of said switch or switches are connected, to thereby vary the length of the signal path and thus vary the resonant frequency.

Abstract
A variable resonator is provided which comprises signal conductor 13 formed on top side surface of dielectric substrate 12, ground conductor layer 11 formed on back side surface thereof and switches 14, wherein signal conductor comprises a plurality of first conductor lines 13-1 and second conductor line 13-2 connected with all of first conductor lines, each first conductor line has a width larger than that of second conductor line to thereby a signal path through which high-frequency electric signal passes and which is longer than length of second conductor line is provided, switches 14 are connected to the ends of first conductor lines, whereby selectively opening and closing switches will electrically disconnect and interconnect interspaces between ends of first conductor lines to thereby vary length of signal path and thus change resonance frequency.

6. A variable phase shifter which comprises a ground conductor, a dielectric, a signal conductor, and at least one switch, wherein:
-
said signal conductor comprises one or a plurality of first conductor lines spaced apart by a predetermined distance from each other and a second conductor line connected with said one first conductor line or all of said first conductor lines;
said first conductor line or lines has or have a width different from that of said second conductor line whereby a signal path through which high-frequency electric signal passes and which is longer than the line length of the second conductor line is defined;
