Abstract

The invention discloses an airborne ultra-wideband omnidirectional printed antenna based on an unmanned aerial vehicle. The antenna comprises a dielectric substrate, a grounding plate, a coaxial feeder line and a square metal sleeve, wherein metal radiation patches are printed on the front and back surfaces of the dielectric substrate respectively, and the metal radiation patches on the front and back surfaces are symmetrically arranged by taking the dielectric substrate as a symmetry axis; the metal radiation patch is connected with the coaxial feeder line, the square metal sleeve is vertically connected with the metal radiation patch and the dielectric substrate, and the square metal sleeve is parallel to the transverse part of the grounding plate; a central feeder needle of the coaxial feeder line is connected with the metal radiation patches on the front and back surfaces of the dielectric substrate, and an outer conductor of the coaxial feed line is connected with the transverse part of the grounding plate. The technology of combining the H-shaped radiator and the grounding body with the stepped gradual change structure at the feeder end is adopted, so that the ultra-wideband impedance matching characteristic is realized; through the top end loading sleeve technology, the bandwidth of the antenna is further broadened, and the miniaturization of the antenna is realized. The antenna has good ultra-wideband characteristics and omnidirectional radiation.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an ultra-wideband omnidirectional printed antenna based on an unmanned aerial vehicle. Background technique [0002] With the continuous expansion of wireless communication systems, equipment on carriers such as drones and ships tends to be miniaturized and integrated. In order to reduce the mutual coupling and interference between antennas in different frequency bands in electronic systems, ultra-wideband omnidirectional printed antennas have become a research hotspot. Ultrashort wave omnidirectional antennas are widely used in various military high-speed mobile platforms such as sea, land and air, but the frequency is low, so the size limitation is the difficulty of antenna design. Due to its compact structure, simple manufacturing process, and easy conformity with the carrier, the planar printed antenna is especially suitable for drones and other places with special requirem...
