Title:
RESONATOR, FILTER, IRREVERSIBLE CIRCUIT ELEMENT, AND COMMUNICATION UNIT
Document Type and Number:
WIPO Patent Application WO/2005/045986
Kind Code:
A1
Abstract:
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.
