Problems solved by technology

However, the distribution of resonance points of the frequency characteristics of this antenna is uneven, and it is difficult to achieve linear phase. In the design, it is necessary to change the size of the metal in the shape of the wine glass and the feeding angle to achieve the impedance matching of the antenna, which is not conducive to the miniaturization design of the antenna.

Description

technical field [0001] The invention relates to an antenna applied in the technical field of wireless communication, in particular to an ultra-wideband antenna with a substrate integrated waveguide feeding structure. Background technique [0002] In recent years, ultra-wideband (UWB) short-range wireless communication has attracted great attention in the field of global communication technology. Compared with other communication technologies, ultra-wideband (UWB) technology has become a very competitive short-distance wireless communication technology due to its high transmission rate, strong anti-multipath interference ability, and favorable multi-functional integration. One of the most powerful and promising technologies. At the same time, ultra-wideband technology has the advantages of low signal power spectral density, high confidentiality, difficult detection, and low system complexity. It is especially suitable for high-speed wireless access and military communication...
