摘要： An antenna beam scan unit includes: a Rotman lens that performs power division and synthesis between plural antenna ports and three or more beam ports; plural antenna elements which are connected to the respective antenna ports and to or from which radio waves are inputted or outputted; plural amplifiers that are connected to the respective beam ports of the Rotman lens and perform amplitude modulation on a signal; input paths for a transmission signal disposed in association with the amplifiers; switches for switching the input paths; and a beam control unit. The input paths include first paths and second paths on which a signal that is out of phase with a signal on the first paths is produced. The beam control unit selects two adjoining beam ports, and can switch the first paths and second paths as the input paths for the two beam ports.

摘要： When a microstrip line is connected with a waveguide, there is a limit to reducing the connection loss by using only a matching box. We have discovered that in a transmission mode line transducer for converting between the TEM waves of the microstrip line and the TE01 waves of the waveguide, if the cross-sections of the microstrip line and the waveguide are substantially the same size, in the case of a 50Ω microstrip line when the characteristic impedance of the waveguide is about 80%, i.e., 40Ω, the line conversion loss can be optimized. Therefore, according to the present invention, the microstrip line is connected with the waveguide using a λ/4 matching box by means of a ridged waveguide having a low impedance and a length of λ/16 or less.
