摘要：
A filter having an unbalanced terminal, a first stripline resonator of which one end is connected to the unbalanced terminal, a second stripline resonator placed to be electromagnetically coupled to the first stripline resonator, and balanced terminals of which both ends are connected to the second stripline resonator, wherein the first stripline resonator and the second stripline resonator are connected by at least one impedance element, and the second stripline resonator is a ½ wavelength resonator substantially having ½ the length of a wavelength of a resonance frequency.
