Title:
PHASE SHIFTER, DISTRIBUTING/SYNTHESIZING DEVICE, ARRAY ANTENNA, AND SECTOR ANTENNA
Document Type and Number:
WIPO Patent Application WO/2017/208382
Kind Code:
A1
Abstract:
This phase shifter enables broadening of the frequency band of a sector antenna or the like, and is provided with: at least one reference conductor to which a reference potential is supplied; a first line conductor which faces the reference conductor so as to constitute a transmission path, and to which a signal is inputted; a second line conductor which is disposed on the first line conductor side so as to face the reference conductor and to constitute the transmission path, and from which a signal is outputted; and a third line conductor which is electrically connected to the first and second line conductors in such a manner as to be able to move relative to the first and second line conductors, and which faces the reference conductor so as to constitute the transmission path, wherein at least one of the first, second, and third line conductors has a portion in which the characteristic impedance is different from that in other portions.
