Huygens source electrically small antenna with reconfigurable frequency agility directional diagram

Abstract

The invention discloses a Huygens source electrically small antenna with a reconfigurable frequency agility directional diagram. The Huygens source electrically small antenna comprises a single-layerdielectric substrate, a split type magnetic dipole unit, a split type unbalanced electric dipole unit and an excitation source unit, wherein the split type magnetic dipole unit is attached to the upper surface of the single-layer dielectric substrate, and the center of the split type magnetic dipole unit coincides with the center of the single-layer dielectric substrate in the vertical direction;the excitation source unit and the split type unbalanced electric dipole unit are both attached to the lower surface of the single-layer dielectric substrate; and each of the split type magnetic dipole unit and the split type unbalanced electric dipole unit is provided with a varactor used for changing a phase relation between the split type magnetic dipole unit and the split type unbalanced electric dipole unit. On the premise of small electricity and low profile, two end-fire Huygens source radiations with the same frequency agility range and opposite radiation directions are realized, and the Huygens source electrically small antenna has good radiation performance in the frequency agility range.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a reconfigurable Huygens source electric small antenna with a frequency agility pattern. Background technique [0002] In recent years, electrically small antennas with reconfigurable performance have been extensively studied. On the one hand, it is proposed to use varactor diodes or PIN switching diodes to realize electrically small antennas with frequency agility or frequency reconfigurable performance. An electrically small antenna with reconfigurable pattern using PIN switching diodes is proposed. However, most current frequency reconfigurable electrically small antennas are difficult to realize the characteristic of pattern reconfiguration, and the electrically small antenna with pattern reconfigurable is also difficult to realize the characteristic of frequency reconfigurability. Therefore, it is very attractive to integrate frequency and pattern reconfigurable features in electric...
