摘要： Without influenced by a symbol rate of a baseband signal, a power consumption is kept low approximately to zero in a phase shifter.In order to control an output signal of an orthogonal modulator, in a phase shifter adding phase to I signal and Q signal inputted to the orthogonal modulator, interchange of the I signal and the Q signal, or interchange of polarities of I signal and Q signal respectively, interchange of both of the above is performed.

摘要： In the sector antenna of the present invention, a feeder waveguide is formed that branches midway from a feeder port to each of a plurality of antennas. This feeder waveguide is formed from a waveguide tube and includes a main feeder line that extends from a waveguide that extends from the feeder port and branches in two directions, and branch feeder lines that each branch in two directions from the two ends of the main feeder line. Sector selection structures are provided for selectively shutting off each branch waveguide by effectively forming conductive walls for blocking the cross section of each of the branch waveguides at positions of each of the branch feeder lines that branch and extend from the main feeder line and from which each branch waveguide begins.
