Abstract

A double stop-band super-broadband antenna basing on the asymmetrical spinous line belongs to the wireless communication technique field. The antenna comprises a medium board (1) and a metal printing antenna arranged at two sides of the medium board (1); wherein the front side of the medium board (1) is arranged with a microstrip feed port (2), a microstrip feed line (3), an asymmetrical spinous line (4) and a microstrip radiating element (5), the microstrip feed line (3) is arranged at the central axis of the medium board (1), the upper part of the microstrip feed line (3) is connected with a microstrip radiating element (5), the lower part of the microstrip feed line (3) is a microstrip feed port (2), and the two sides of the middle part of the microstrip feed line (3) are arranged withasymmetrical spinous lines (4); and the lower part at the back side of the medium board (1) is arranged with an earth unit (6). The invention can effectively cover the request frequency band of FCC, namely 3.1-10.6GHz, at the same time two stop-bands can be generated in the frequency band. The antenna of the invention has the characters of low cost, simple structure and small volume.

Description

technical field

[0001] The invention relates to an ultra-wideband antenna technology applicable to short-distance wireless communication and data transmission. The antenna can effectively solve the problem that the broadband communication system is interfered by other existing narrowband communication system signals. Background technique

[0002] In recent years, ultra-wideband (UWB) short-range wireless communication has attracted great attention in the field of global communication technology. Ultra-wideband communication technology has become one of the most competitive and promising technologies for short-distance wireless communication due to its high transmission rate, strong anti-multipath interference ability, high confidentiality, and multi-functional integration. In February 2002, after the FCC released the use of UWB without a license, UWB technology quickly became a hot spot in the research and development of the international wireless communication field, and wa...
