Horn antenna -integrated MMIC package and array antenna

摘要

PROBLEM TO BE SOLVED: To reduce the manufacturing cost of an MMIC integrating horn antenna using a multilayer substrate.;SOLUTION: In a multilayer substrate 11 laminating a plurality of dielectric sheets 11b, a horn antenna 12 flared in a fan shape only in the H in-plane direction or the E in-plane direction of radiation electromagnetic wave, and a cavity 16 for housing an MMIC are provided so that the opening end 12a of the horn antenna is in the in-plane direction of the multilayer substrate 11. Since the number of the dielectric sheets 11b which require cutting for obtaining the horn antenna is decreased, the manufacturing cost of the horn antenna can be reduced. Furthermore, the number of the dielectric sheets 11b requiring the cutting does not increase even if the length of the horn antenna 12 is lengthened.;COPYRIGHT: (C)2014,JPO&INPIT
