Ultra-wideband conformal multi-dielectric-body dielectric resonator antenna and working method

Abstract

The invention provides an ultra-wideband conformal multi-dielectric-body dielectric resonator antenna and a working method. The ultra-wideband conformal multi-dielectric-body dielectric resonator antenna comprises a dielectric resonator, a floor, a dielectric substrate, a feed port, a feed slot and a feed line. The floor and the dielectric substrate are arc-shaped. The dielectric resonator comprises a first dielectric resonator and a second dielectric resonator. The first dielectric resonator and the second dielectric resonator are arc-shaped and conformal with the arc of the floor. The firstdielectric resonator and the second dielectric resonator have the same arc radius and different radians. The dielectric constants of the first dielectric resonator and the second dielectric resonatorare different. The antenna is fed by the feed line from the feed port, and then, electromagnetic wave energy is coupled and conducted to the first dielectric resonator and the second dielectric resonator on the upper surface through the feed slot in the floor. The center of the feed slot coincides with the center of the floor and coincides with the center of the whole dielectric resonator. The ultra wide band and stable gain performance are achieved by adopting the convex floor and the convex multi-dielectric-body dielectric resonator.
