TM-mode wearable arc-shaped dielectric resonator antenna adopting conformal feed

Abstract

The invention discloses a TM-mode wearable dielectric resonator antenna adopting conformal feed. The antenna comprises a dielectric resonator, a bottom plate, a dielectric substrate, and a feeder, wherein the bottom plate and the dielectric resonator are conformal; the dielectric resonator is fixed in the middle of the outer surface of the dielectric substrate; the feeder is located on the upper surface of the dielectric substrate, and extends to one side surface of the dielectric resonator so as to be conformal with the dielectric resonator; the inner and the outer surfaces of the dielectricsubstrate are respectively adhered to the bottom plate and the dielectric resonator; and the antenna is fed by the feeder, and electromagnetic wave energy is transmitted to the dielectric resonator through the feeder. The antenna disclosed by the invention has the advantages that the substrate adopts a ring-shaped structure, which is wearable, so that extensive application fields and flexible application scenarios can be achieved; through the conformal structure, the profile size is not enlarged when the dimensions of the bottom plate are adjusted, so that the property of high gains or wide beams can be achieved; the bandwidth is larger than that of a microstrip antenna; and the conformal feeder on the substrate and the dielectric resonator can be further used for assembly alignment, so that manufacturing and processing are easier.
