Radar apparatus and method of manufacturing the same

PURPOSE: A radar device and an assembly method thereof are provided to increase the degree of freedom in an installation position of radar, as supplying a structure capable of reducing the number and size of parts. CONSTITUTION: A radar device(100) consists of the first PCB(120), the second PCB(140) and a base plate(130). A radar antenna unit is arranged in an upper side of the first PCB, a baseband circuit unit is arranged in a lower side. An RF circuit unit penetrating through a hole is wire-bonded. A signal processing unit is arranged in the second PCB. A protrusion unit is formed in the upper side of the base plate. The rest part except for the protrusion unit is allocated so the baseband circuit unit is to be located. [Reference numerals] (110) Cavity; (120) First PCB; (130) Base plate; (140) Second PCB
