Miniaturized single-notch dual-band ultra-wideband antenna

Abstract

The invention discloses a miniaturized single-notch dual-band ultra-wideband antenna, which comprises a dielectric substrate, a radiation patch, a microstrip feeder line and a rectangular grounding plate, and is characterized in that the radiation patch and the microstrip feeder line are both printed on the front surface of the dielectric substrate, and the rectangular grounding plate is printed on the back surface of the dielectric substrate; wherein the radiation patch adopts a rectangular basic pattern, two rectangular patches are dug in the middle of the rectangle, and then one rectangularpatch is dug below each rectangular patch; the feeder line is arranged at the lower right position of the rectangular radiation patch; a rectangular groove is cut off from the grounding plate. The combination of the radiation patch and the feeder line broadens the bandwidth of the antenna. The stop band is generated by slotting the radiation patch, the interference of different narrowband signalsis effectively filtered, the compatible cooperative communication of an ultra-wideband system and other narrowband communication systems is realized, and the miniaturized single-notch dual-band ultra-wideband antenna has the advantages of simple structure, good radiation characteristic and strong anti-interference capability, and has omnidirectional radiation characteristic in a passband frequency band.

Description

Technical field[0001]The invention belongs to the technical field of wireless communication, and in particular relates to a miniaturized ultra-wideband antenna with single notch characteristics.Background technique[0002]In recent years, wireless communication technology has been developed and updated with the needs of people's work and life, and the development trend of miniaturization, low cost, and high efficiency of terminal equipment has gradually become prominent, making antennas bound to move towards the goal of miniaturization and broadband. Ultra-wideband technology is widely used in radar remote sensing and military communications because of its advantages of high transmission rate, low power consumption, and high resolution. The Federal Communications Commission (FCC) of the United States was established in 1934 as an independent agency of the US government. Since the FCC allocated the ultra-wideband frequency band from 3.1 to 10.6 GHz to the field of civilian communicatio...
