Abstract

The invention discloses a Huygens source electric small antenna with a reconfigurable frequency agile pattern, comprising a single-layer dielectric substrate, a slit-type magnetic dipole unit, a slit-type unbalanced electric dipole unit, and an excitation source unit; 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 magnetic dipole unit The unbalanced electric dipole units are all attached to the lower surface of the single-layer dielectric substrate; the split-type magnetic dipole unit and the split-type unbalanced electric dipole unit are all provided with one for changing the split-type magnetic dipole. A varactor diode for the phase relationship of the cell to the split-type unbalanced electric dipole cell. Under the premise of small electricity and low profile, the invention realizes the radiation of two end-fire Huygens sources with the same frequency agility range and opposite radiation directions, and has good radiation performance within the frequency agility range.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a Huygens source electric small antenna with a reconfigurable frequency agile pattern. Background technique [0002] In recent years, electrically small antennas with reconfigurable properties have been extensively studied. On the one hand, the use of varactor diodes or PIN switch diodes to realize electrically small antennas with frequency agility or frequency reconfigurability has been proposed. An electrically small antenna with reconfigurable pattern using PIN switch diode is proposed. However, it is difficult for most of the current frequency reconfigurable electric small antennas to achieve pattern reconfigurable characteristics, and it is also difficult for electric small antennas with reconfigurable patterns to achieve frequency reconfigurable characteristics. Therefore, it is very attractive to integrate frequency and pattern reconfigurable properties in electrically small anten...
