Title:
RADIAL LINE FEED DIELECTRIC RESONANT ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2016/109920
Kind Code:
A1
Abstract:
Disclosed is a radial line feed dielectric resonant antenna array, comprising a surface-slotted radial line waveguide (1), a feed probe (2) and a dielectric resonant antenna array (3). The surface-slotted radial line waveguide (1) comprises an upper-layer slotted metal plate (1a) and a lower-layer metal bottom plate (1b). The feed probe (2) comprises a metal bar (2a) and a radio antenna terminal (2b) connected to the metal bar (2a). The feed probe (2) is located at the axial centre position of the surface-slotted radial line waveguide (1). One end of the radio antenna terminal (2b) extends out of the surface-slotted radial line waveguide (1). The dielectric resonant antenna array (3) is located right above the upper-layer slotted metal plate (1a). The dielectric resonant antenna array (3) comprises multiple unit dielectric resonators. The radial line feed dielectric resonant antenna array provided in the present invention achieves linearly polarized or circularly polarized electromagnetic wave radiation using a single feed method, has a simple structure and obtains a high gain and high aperture efficiency.
