Ultra-wide bandwidth planar miniaturization micro-strip antenna

Abstract

The invention discloses an ultra-wide bandwidth planar miniaturization micro-strip antenna which comprises a medium plate, a radiation patch unit, a grounding plate and a micro-strip feeder line. The radiation patch unit and the micro-strip feeder line are arranged on the obverse side of the medium plate. The grounding plate is arranged on the reverse side of the medium plate. Through arrangement of the regular rectangular radiation patch unit, flow direction of current of a wide-band antenna is changed, and broadband and miniaturization of the wide-band antenna are achieved compared with the method that two stacked protruded grooves are formed in a rectangular gradual cutting corner radiation patch. Low-frequency stage band width is expanded, and the size of the wide-band antenna is reduced. The wide-band antenna can achieve ultra-wide bandwidth features within 3GHz-19GHz. The wide-band antenna is simple in structure, low in section, easy to install and integrate, and easy to process. The reflection loss of the wide-band antenna within the frequency band scope of 3GHz-19GHz is smaller than minus 10 decibels. In addition, the ultra-wide bandwidth planar miniaturization micro-strip antenna is convenient to operate and simple in structure, and has good application value.

Description

technical field [0001] The invention belongs to the field of microstrip antenna manufacture, in particular to an ultra-wideband planar miniaturized microstrip antenna. Background technique [0002] Ultra-wideband antenna is the main equipment of modern warfare electronic reconnaissance system and electronic jamming system. In terms of electronic reconnaissance, due to the wide application of frequency modulation technology, the working bandwidth of electronic reconnaissance system is required to be wider and wider, and the high frequency band is required to be extended to 40GHz-110GHz The CR2740A radar intelligence and reconnaissance system developed by Israel Elistra Company has a frequency coverage of 0.5GHz-40GHz. In terms of electronic interference, the radar's stealth technology and anti-stealth technology are mainly aimed at the microwave frequency band of 1-20GHz. Raytheon's AN / The ALQ.142 integrated radio frequency jamming system has been providing 2GHz-25GHz radio ...
