RESONATOR, FILTER, IRREVERSIBLE CIRCUIT ELEMENT, AND COMMUNICATION UNIT

A dielectric substrate (1) is provided with first and second conductor openings (AP1, AP2) communicating through a first slit (SL1), and third and fourth conductor openings (AP3, AP4) communicating through a second slit (SL2) such that the slits (SL1) and (SL2) intersect each other. Two resonance mo...

Summary:A dielectric substrate (1) is provided with first and second conductor openings (AP1, AP2) communicating through a first slit (SL1), and third and fourth conductor openings (AP3, AP4) communicating through a second slit (SL2) such that the slits (SL1) and (SL2) intersect each other. Two resonance modes, i.e. an even mode where a field vector is directing between (AP1)-(AP3) and (AP4)-(AP2), and an odd mode where a field vector is directing between (AP3)-(AP2) and (AP1)-(AP4), or two resonance modes, i.e. an X mode where the field vector is directing between (AP1)-(AP2) and a Y mode where the field vector is directing between (AP3)-(AP2), are thereby generated. Un substrat diélectrique (1) comprend des première et deuxième ouvertures de conduction (AP1, AP2) qui communiquent à travers une première fente (SL1), ainsi que des troisième et quatrième ouvertures de conduction (AP3, AP4) qui communiquent à travers une seconde fente (SL2) de sorte que les fentes (SL1) et (SL2) se croisent. Deux modes de résonance, à savoir un mode pair où le vecteur de champ est dirigé entre (AP1)-(AP3) et (AP4)-(AP2), et un mode impair où le vecteur de champ est dirigé entre (AP3)-(AP2) et (AP1)-(AP4), ou deux modes de résonance, à savoir un modeX où le vecteur de champ est dirigé entre (AP1)-(AP2) et un mode Y où le vecteur de champ est dirigé entre (AP3)-(AP2), sont ainsi obtenus.
