Abstract:
A sharing device comprising:at least a first filter and a second filter; said first filter including a dielectric substrate, a first conductor formed on one major surface of said dielectric substrate, a second conductor formed on the other major surface of said dielectric substrate, a first opening formed in said first conductor to expose said dielectric substrate from said first conductor, a second opening formed in said second conductor to expose said dielectric substrate from said second conductor, a first conductive plate arranged to be spaced apart from said first conductor and to cover at least said first opening, a second conductive plate arranged to be spaced apart from said second conductor and to cover at least said second opening, a resonance portion determined by said first opening and said second opening, and input/output means coupled to said resonance portion, and said second filter including a dielectric substrate, a first conductor formed on one major surface of said dielectric substrate, a second conductor formed on the other major surface of said dielectric substrate, a first opening formed in said first conductor to expose said dielectric substrate from said first conductor, a second opening formed in said second conductor to expose said dielectric substrate from said second conductor, a first conductive plate arranged to be spaced apart from said first conductor and to cover at least said first opening, a second conductive plate arranged to be spaced apart from said second conductor and to cover at least said second opening, a resonance portion determined by said first opening and said second opening, and input/output means coupled to said resonance portion; common input/output means which connects one of said input/output means of said first filter to one of said input/output means of said second filter; and an electromagnetic wave absorbing member arranged at at least one of a position between said first and second conductive plates of said first filter and a position between said first and second conductive plates of said second filter.
