Dual-band dielectric resonator antenna for millimeter wave application

Abstract

The invention discloses a dual-band dielectric resonator antenna for millimeter wave application, and the antenna comprises a laminated dielectric resonator which consists of a high-dielectric-constant dielectric sheet and a low-dielectric-constant second dielectric substrate, and the dielectric sheet is located on the upper surface of the second dielectric substrate; a microstrip feed panel, composed of a metal ground, a first dielectric substrate and a microstrip line. The microstrip feed plate is positioned below the laminated dielectric resonator. The metal ground and the microstrip line are located on the upper and lower opposite surfaces of the first dielectric substrate. One end of the microstrip line extends to the edge of the first dielectric substrate, is connected with the feeder line and feeds the stacked dielectric resonator through the gap, and the gap is formed in the metal ground and is perpendicular to the microstrip line. According to the invention, the microstrip line is used for feeding the laminated dielectric resonator through the gap, two resonance modes are formed, and the problem that the dielectric antenna cannot realize millimeter wave dual-band coverageon the basis of high radiation efficiency and low profile structure is solved.
