Microwave receiving antenna and microwave receiving antenna array

摘要

PROBLEM TO BE SOLVED: To provide an antenna for microwave reception capable of securing sufficient reception sensitivity and sufficiently reducing interference with a neighboring antenna if arrayed.SOLUTION: A dipole antenna is formed by printing dipoles 21 and 22 in front portions on both side faces of a dielectric substrate 20, respectively, and a reception circuit 80 is included in a rear portion on one side face. A laminate 40 is formed from the dielectric substrate 20 and a pair of dielectrics 30 and 34 laminated in the front portions where the dipoles 21 and 22 are formed. A waveguide 100 is formed by covering four sides of the laminate 40 with a conductor shield, and evanescent waves are received. Thus, the sufficient reception sensitivity can be secured and the interference with the neighboring antenna is sufficiently reduced if arrayed.
