Abstract

The invention discloses an ultra wide band antenna. The ultra-wideband antenna is arranged on a communication device comprising a metal component, and the ultra-wideband antenna comprises a first dielectric substrate, a main radiation patch, a parasitic radiation patch and an impedance matching patch, the first dielectric substrate is provided with a first conductive via hole; the main radiation patch is arranged on the upper surface of the first dielectric substrate and is electrically connected with the first conductive via hole; the parasitic radiation patch is arranged on the lower surface of the first dielectric substrate; the impedance matching patch and the parasitic radiation patch are located on the same plane and electrically connected with the first conductive via hole, the parasitic radiation patch surrounds the impedance matching patch and is isolated from the impedance matching patch, and the impedance matching patch is provided with a feeding point. Wherein the parasitic radiation patch is configured to couple energy from the main radiation patch, and the parasitic radiation patch is configured to generate a notch frequency close to a notch frequency generated by the main radiation patch so as to broaden a frequency band bandwidth.

Description

technical field [0001] The present application relates to the field of antenna technology, and in particular, to an ultra-wideband antenna. Background technique [0002] Ultra Wide Band (UWB) is a wireless carrier communication technology, which is mainly used in short-distance high-speed data communication of about 10 meters. It uses nanosecond to microsecond non-sine wave narrow pulses to transmit data. Very low power signals are transmitted over a wide frequency spectrum. [0003] At present, UWB antennas mostly adopt a single-radiation patch design (ie, a single-patch antenna), wherein the radiation patch is located above the dielectric substrate, and the antenna reference ground is located on the bottom surface of the dielectric substrate. However, the single patch antenna has the problem of narrow bandwidth due to its limited physical properties. Therefore, the relevant industry proposes to increase the VSWR bandwidth of the antenna by changing the shape of the taper...
