<p>PURPOSE:To provide a radar module wherein the number of part items is decreased, dimensions are reduced and resultant cost reduction is devised. CONSTITUTION:A single diode mixer 16 is connected to a high frequency signal generator such as an FM signal generator 11 via a non-radioactive dielectric line 22 and the like. A directional coupler 13 is formed of the non-radioactive dielectric line 22 and the like and a curved shape non-radioactive dielectric line 23 and the like arranged in the vicinity thereof. A transmission antenna 14 and a receiving antenna 15 of a non-radioactive dielectric line are connected respectively to both ends of the curved shape non-radioactive dielectric line 23.</p> |
