Abstract

The invention discloses a novel stop band gap ultra wide band antenna, wherein the antenna comprises a polygan gap antenna and a combined trap wave structure, namely, a combined trap wave is generated by opening a C-shaped gap on the T-shaped micro-strip feeder which serves as a feed unit and adding micro-strip wires in the polygan gap. The polygan gap antenna can generate ultra wide band characteristics and adopts a double frequency resonance oscillation trap wave structure similar to a second order filter to realize narrower stop band. Compared with the prior art, the stop band ultra wide band antenna can realize good filtering characteristics and has the advantages of small size and low cost.

Description

technical field [0001] The invention relates to an ultra-wideband (UWB) antenna, in particular to a novel stopband slot UWB antenna. Background technique [0002] Ultra-wideband (UWB) technology originated from the pulse communication technology that emerged in the 1960s. It uses ultra-short pulses with extremely wide spectrum for communication, also known as baseband communication and carrier-free communication. It is mainly used in military radar, positioning and communication systems. . In February 2002, the U.S. Federal Communications Commission (FCC) opened the 3.1GHz-10.6GHz frequency band to ultra-wideband communications, and approved UWB technology for civilian use; subsequently, Japan opened the ultra-wideband frequency band in August 2006. Because UWB technology has the characteristics of high transmission rate (1Gbit / s), strong anti-multipath ability, low power consumption, low cost, strong penetration ability, low probability of interception, and sharing spectru...
