Abstract

The invention relates to an ultra-wideband antenna with double notch characteristics. The antenna comprises a top radiation patch layer, an intermediate dielectric substrate and a bottom grounding plate. The top radiation patch layer, the intermediate dielectric substrate and the bottom grounding plate are tightly connected to form an antenna whole body, wherein the top radiation patch layer is connected with a microstrip transmission line, a C-shaped gap with an upward opening is etched in one side, close to the microstrip transmission line, of the top radiation patch layer so as to realize WLAN frequency band notch characteristics, and a right-angle U-shaped gap is etched in the microstrip transmission line so as to realize X-band notch characteristics. According to the invention, the notch effect of the antenna can be improved, so that the antenna forms good notch characteristics in two narrow-band frequency bands of a wireless local area network and an X-band satellite.

Description

technical field [0001] The invention relates to an ultra-wideband antenna, in particular to an ultra-wideband antenna with double notch characteristics, which can communicate with a WLAN narrowband system and a WiMAX narrowband system. Background technique [0002] With the rapid development of mobile communication technology, the demand for various data services in the era of the Internet of Things has surged, and higher requirements have been placed on the data storage capacity and information transmission speed of modern wireless communication. At the same time, modern electronic equipment is moving toward miniaturization and integration.
