Abstract

The embodiment of the invention provides a handheld interference unit and an interference unit antenna thereof. The interference unit antenna comprises: an antenna body which comprises a first dielectric plate and a radiation patch formed on the surface of the first dielectric plate, wherein a radiation signal of the interference unit antenna is transmitted in the extension direction of the first dielectric plate, and is output from the end part of the first dielectric plate; and a metamaterial antenna housing arranged in parallel with the first dielectric plate at an interval and corresponds to the position of the radiation patch, wherein the metamaterial antenna housing covers the radiation patch in the extending direction of the first dielectric plate so as to suppress surface waves radiated from the radiation patch.

Description

technical field [0001] The invention relates to the field of antenna equipment, in particular to a hand-held jammer and a jammer antenna thereof. Background technique [0002] Most of the existing jammer antennas have the problems of large antenna size and low working bandwidth. Most of them are only suitable for omnidirectional antennas, and the radiation performance of directional antennas cannot meet the increasing equipment requirements. Contents of the invention [0003] In view of this, the object of the present invention is to provide a hand-held jammer and its jammer antenna, which can reduce side lobes and gather beams by arranging a metamaterial radome for suppressing surface waves on both sides of the antenna body, thereby Increase the gain of the antenna at the root. [0004] One embodiment of the present invention provides a jammer antenna, including: [0005] An antenna body, the antenna body includes a first dielectric plate and a radiation patch formed on...
