PHASE SHIFTER, ANTENNA AND RADIO APPARATUS

摘要

A phase shifter, which reduces the loss of transmission/reception signals, includes: a linear conductor (211); a conductor (212) curved to form an arc of a radius Ro; and a conductor (214) that has a curving portion (214a) curved to form an arc of a radius Ri, and that also has an extending portion (214b) linearly extending from one end of the curving portion (214a). The phase (phase shift amount) varies depending on the rotation of the conductor (214) about a rotation axis (220) which causes the position of a part (±) where the curving portion (214a) overlaps the conductor (211) to move along the curving portion (214a) and the position of a part (²) where the extending portion (214b) overlaps the conductor (212) to move along the conductor (212).
