摘要： PROBLEM TO BE SOLVED: To solve problems wherein a method of constituting a resonator by connecting a high permittivity block to a microstrip line is often used in a method of using the resonator of the high permittivity block, but it is necessary to adjust the relative positions of the microstrip line and high permittivity block to obtain optimum oscillating conditions, and a method of constituting a PLL circuit causes an increase in the number of components, which causes a cost increase and enlargement of a component area to make miniaturization difficult.
SOLUTION: This radar device includes an oscillator for generating a transmission wave, and a mixer for mixing the transmission wave propagated from the oscillator, with a received wave of the transmission wave reflected from an object and returned. The oscillator propagates the transmission wave to the mixer through a delay circuit. The delay amount of the delay circuit may be variably controlled. A line may be provided for propagating the transmission wave to the mixer without going through the delay circuit.

摘要： PROBLEM TO BE SOLVED: To solve the problem that in a millimeter wave band transceiver using a waveguide as a connection line to an antenna, it is necessary to perform conversion between a microstrip line of TEM wave transmission and a waveguide of TE01 mode wave transmission and there is a limit of reducing the conversion loss using only a λ/4 matching circuit for connecting the microstrip line with the waveguide. SOLUTION: In the conversion between the microstrip line of TEM wave transmission and the waveguide of TE01 mode wave transmission, if the cross-sections are substantially the same size, in the case of a 50 Ω microstrip line when the characteristic impedance of the waveguide is about 80%, i.e., 40 Ω, the line conversion loss can be optimally reduced. Therefore, the microstrip line is connected to the waveguide using a λ/4 matching circuit via a ridged waveguide having a low impedance and a length of λ/16 or less. COPYRIGHT: (C)2008,JPO&INPIT

解决方案：在TEM波传播的微带线与TE01模式波传输的波导之间的转换中，如果横截面基本相同的尺寸，则在50Ω微带线的情况下，当特性阻抗波导约为80％，即40Ω，可以最佳地降低线路转换损耗。因此，微带线通过λ/ 4匹配电路通过具有低阻抗和长度为λ/ 16或更小的脊波导连接到波导。版权所有（C）2008，JPO＆INPIT
