Problems solved by technology

However, when the working environment of the notch antenna changes (for example, other wireless protocols disappear), due to the addition of the notch frequency band, the overall working frequency band of the antenna is narrowed, which will lead to a waste of frequency resources

Abstract

The invention discloses an ultra-wideband (UWB) planar monopole antenna with reconfigurable trap characteristic. The UWB planar monopole antenna with the reconfigurable trap characteristic comprises a dielectric substrate (1), and a metal coating and two micro electronic mechanical system (MEMS) switches which are positioned on the upper surface of the dielectric substrate (1). The metal coating comprises a radiation unit (2), a coplanar waveguide feeder (3) and a coplanar waveguide floor, wherein the coplanar waveguide floor comprises a first coplanar waveguide floor (7) and a second coplanar waveguide floor (8); and the radiation unit (2) forms a C-like groove (4) by etching. The antenna provided by the invention has a simple and compact structure and can switch the trap characteristic of the antenna by controlling on and off of the two MEMS switches so as to effectively work on the UWB frequency band, and realize generation or disappearance of a trap frequency band, thus improving the utilization ratio of the frequency band and the communication efficiency.

Description

technical field [0001] The invention relates to a planar ultra-wideband antenna and frequency reconfigurable antenna technology in the field of wireless communication, in particular to an ultra-wideband planar monopole antenna with reconfigurable notch characteristics. Background technique [0002] Due to the rapid development of modern communication systems, wireless technology is facing more and more severe challenges. Restricted by adverse factors such as narrow frequency bandwidth, low transmission rate, and poor security performance, traditional communication technologies are increasingly difficult to adapt to the requirements of new communication methods. Ultra-wideband (UWB) technology has the advantages of large system capacity, good confidentiality, and high transmission rate that other wireless technologies cannot match. In recent years, it has been widely developed and applied in the field of communication. As an important part of UWB communication, UWB antenna p...
