Problems solved by technology

However, in order to obtain a wider impedance bandwidth for planar monopole antennas, the vibrator usually has a larger width. As the operating frequency increases, the omnidirectionality of the radiation pattern of the antenna will become worse due to the difference in the length of the field transmission path.

Abstract

The invention relates to an ultra wide band antenna, in particular to a novel ultra wide band folding monopole antenna with an omni-directional radiation function. The novel ultra wide band folding monopole antenna with the omni-directional radiation function achieves the omni-directional variation characteristic of a directional diagram at the high-frequency end of a planar monopole antenna. A traditional planar monopole is bent to form an S-shaped monopole; a high-frequency-band radiation directional diagram of the antenna is improved, the lateral dimension of a vibrator is lowered, and the size of a floor is reduced at the same time.

Description

technical field [0001] The invention relates to an ultra-wideband antenna, in particular to a novel ultra-wideband folded monopole antenna with omnidirectional radiation. Background technique [0002] With the development of ultra-wideband communication systems, the advantages of high data transmission rate and low loss have attracted more and more attention from researchers. Since the United States Federal Communications Commission (US-FCC) approved the application of the 3.1-10.6GHz frequency band as an ultra-wideband communication technology in 2002, scholars at home and abroad have conducted a lot of research on it. As an important front-end component of UWB communication systems, the design of UWB antennas has also become a research hotspot in recent years. Among various types of antennas, the planar monopole antenna exhibits good broadband characteristics due to its small size and easy integration. However, in order to obtain a wider impedance bandwidth for planar mo...
