Abstract

The present invention provides an ultra wideband differential antenna with a band-notched characteristic. The ultra wideband differential antenna includes a dielectric substrate, a grounding plate located at the lower surface of the dielectric substrate, and a feeding layer located at the upper surface of the dielectric substrate; the feeding layer comprises two radiation units which are in bilateral symmetry; each radiation unit includes a microstrip feeder line and a radiation patch, wherein the microstrip feeder line is connected with the radiation patch; the grounding plate comprises four cut corners which are located at the edge of the grounding plate and are radially symmetric, a circular slot located at the middle of the grounding plate, and two C-shaped metal strips disposed in the circular slot and are in bilateral symmetry; the C-shaped metal strips are parallel to the edge of the circular slot; and gaps are left between the C-shaped metal strips and the edge of the circular slot. The ultra wideband differential antenna with the band-notched characteristic of the invention is miniaturized and achieves a band-notched function; the radiation characteristic of the antenna in high frequency bands is optimized and improved; and the gain of the antenna in the high frequency bands is also improved.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to an ultra-wideband differential antenna with notch characteristics. Background technique [0002] Since the Federal Communications Commission announced the use of the 3.1-10.6GHz frequency band in the commercial field in 2002, ultra-wideband (UWB) communication systems with high data transmission rates, low cost, low power consumption, and strong anti-interference capabilities have developed rapidly. UWB antennas It has become a research hotspot of international scholars in recent years. However, within the coverage of ultra-wideband, some frequency bands have already been occupied, such as WiMAX (3.4-3.6 GHz), and WLAN (5.15-5.35 GHz) and (5.725-5.825 GHz). Therefore, the UWB antenna may interfere with the existing communication network during operation. [0003] Therefore, there is a need for an ultra-wideband differential antenna with notch characteristics tha...
