Abstract

The invention provides a miniaturization double double-band-elimination ultra-wide-band microstrip antenna, and relates to the filed of ultra-wide-band wireless communication. The miniaturization double-band-elimination ultra-wide-band microstrip antenna comprises a dielectric substrate, a feeder line which is arranged on the dielectric substrate and is used for receiving electromagnetic waves, a radiating unit which is connected with the feeder line and is used for radiating the electromagnetic waves, a grounding plate which is arranged on the lower surface of the dielectric substrate, and two 6-shaped resonance circuits which are arranged on the dielectric substrate and are located on two sides of the feeder line in an axial symmetry mode. The upper end and the lower end of the radiating unit are respectively provided with a non-equivalent-width groove which is shaped like a Chinese character 'gong' and an outer-convex-shaped transition groove. The grounding plate is provided with a stepped groove which is matched with the outer-convex-shaped transition groove. The grounding plate and the radiating unit are designed to be two transition grooves, a standing-wave ratio band width is made to reach 2.4GHz - 11.6GHz, and a 131% relative standing-wave ratio band width is achieved. The non-equivalent-width groove which is shaped like the Chinese character 'gong' and the two 6-shaped resonance circuits respectively correspond to one fourth of 3.3GHz - 3.8GHz and one fourth of 5.0GHz - 6.0GHz, and the trapped wave function and the double-band-elimination design of the antenna are achieved.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband wireless communication, in particular to a miniaturized dual-band-stop ultra-wideband microstrip antenna. Background technique [0002] With the development of society and the advancement of science and technology, the application frequency band of radio has also been continuously expanded, thereby promoting the emergence of ultra-wideband electromagnetics. UWB technology has many advantages that narrowband systems cannot match, such as: high data rate, low system cost and anti-multipath effect, etc. The unique advantages make UWB system one of the most competitive and promising technologies. [0003] UWB antennas have a wide range of applications. It can be used for GPRS global positioning, resource and environment detection, satellite communication, radar, etc. In recent years, there have been many studies on short-distance wireless communication. The advantages of high data rate can be ...
