MILLIMETER-WAVE BROADBAND SUBSTRATE INTEGRATED HYBRID DIELECTRIC RESONATOR ANTENNA

A millimeter-wave broadband substrate integrated hybrid dielectric resonator antenna is provided. The hybrid antenna includes: a first dielectric substrate with high dielectric constant, a second dielectric substrate with low dielectric constant, and a third dielectric substrate with low dielectric constant sequentially stacked from top to bottom. The first dielectric substrate and the second dielectric substrate are adhered by a first adhesive sheet; the second dielectric substrate and the third dielectric substrate are adhered by a second adhesive sheet; a middle of a top surface of the second dielectric substrate is printed with a metal ring patch; a top surface of the third dielectric substrate is formed with a metal ground plane, and the metal ground plane is etched with a feed slot; and a bottom surface of the third dielectric substrate is disposed with a microstrip line.
