Abstract:
1. An electronic chip component comprising: a chip including upper and lower surfaces, a pair of side surfaces, and first and second end surfaces facing each other; a resonator electrode provided in the chip; input and output electrodes extending in a vertical direction of the chip, which are coupled or connected to the resonator electrode; and a first ground electrode disposed around the chip, the first ground electrode having a tubular shape so as to enclose the resonator electrode; wherein the input and output electrodes are disposed at end portions or inner sides of the tubular first ground electrode, such that the input and output electrodes are not electrically connected to the first ground electrode; the electronic chip component further includes at least a pair of second ground electrodes which are disposed on both sides of at least one of the input electrode and the output electrode and which are electrically connected to the first ground electrode; the resonator electrode is arranged so as to generate a plurality of resonance modes which are not degraded and the resonator electrode includes a through hole for coupling the plurality of resonance modes, whereby a band-pass filter is provided; and the electronic chip component further includes a third ground electrode which extends in the through hole so as not to be in contact with the resonator electrode and which is electrically connected to the first ground electrode.
