Abstract

PURPOSE:To make it possible to manufacture a dielectric horn-antenna at low cost by providing a metal coating on the whole surface except parts corresponding to a radio-wave feed point of a dielectric block formed in a horn-antenna shape and an opening surface. CONSTITUTION:Horn-shaped dielectric 1 is formed by molding resin with excellent high-frequency characteristics and horn external-surface metal coating 2 is provided on the external circumference except feed point 3 and opening surface 4 to form a horn-antenna. Then, case 5 with an incorporated radar unit circuit is made of the same material as this dielectric and on its inside surface, the metal coating provided on the external circumference of this antenna is provided as case inside metal coating 6 to obtain the integral structure of the antenna and case. At horn- antenna feed point 3 in case 5, oscillation part 7 is set and additional circuit 8 is built in and connected. Then, reverse case cover 9 is fixed by set screws and the case is hermetically sealed after its inside is substituted with dry air, etc. For airtight measures, packing 10 is provided. Consequently, a radar unit including the horn- antenna can be manufactured at low cost and its reliability can be improved.
