Kind Code:
A
Abstract:
To solve the problem that circuit scale of a radio apparatus has been large.
A slot antenna includes a conductor plate comprising a slot with first, second, third and fourth connection points and a resonance capacitor. Impedance determined by positions of the first and second connection points is substantially equal to impedance of a first circuit, and impedance determined by positions of the third and fourth connection points is substantially equal to impedance of a second circuit.
