Abstract

Embodiments of the present invention provide a handheld jammer and its jammer antenna, including: an antenna body, the antenna body includes a first dielectric plate and a radiation patch formed on the surface of the first dielectric plate, the jammer antenna The radiated signal is transmitted along the extension direction of the first dielectric plate, and is output from the end of the first dielectric plate; a metamaterial radome, the metamaterial radome is arranged in parallel with the first dielectric plate, and Corresponding to the position of the radiation patch, the metamaterial radome covers the radiation patch in the extending direction of the first dielectric plate to suppress surface waves radiated from the radiation patch.

Description

technical field [0001] The present invention relates to the field of antenna equipment, in particular to a hand-held jammer and its jammer antenna. Background technique [0002] Most of the existing jammer antennas have problems that the size of the antenna is too large and the working bandwidth is not wide, and most of them are only suitable for omnidirectional antennas, and the radiation performance of directional antennas cannot meet the increasing equipment requirements. SUMMARY OF THE INVENTION [0003] In view of this, the purpose 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 metamaterial radomes for suppressing surface waves on both sides of the antenna body. Increase the gain of the antenna at the root. [0004] An embodiment of the present invention provides a jammer antenna, including: [0005] an antenna body, the antenna body includes a first dielectric plate and a r...
