Title:
RESONATOR, FILTER, AND FILTER BANK
Document Type and Number:
WIPO Patent Application WO/2018/225126
Kind Code:
A1
Abstract:
A ground conductor (3) is disposed on one surface of a flat plate-like dielectric substrate (4). A linear conductor (1) is provided on the other surface of the dielectric substrate (4) so as to oppose the ground conductor (3). A floating conductor (2) is provided between the linear conductor (1) and the ground conductor (3). The linear conductor (1) has a length of about 1/2 wavelength in an operating frequency, and has a bending portion (11) for making the linear distance between both end portions thereof a distance not more than 1/8 wavelength in the operating frequency. The floating conductor (2) is configured such that the length thereof in the direction parallel with the longitudinal direction of the linear conductor (1) is about 1/4 wavelength in the operating frequency.
