Abstract

The invention provides a miniaturized ultra-broadband and bluetooth printed antenna, which includes a dielectric substrate, a printed monopole antenna plate, a metal floor and a microstrip feeder conduction tape, the printed monopole antenna plate is arranged on the front of the dielectric substrate, and the printed monopole antenna The board includes first and second antenna units, the first and second antenna units are respectively configured to radiate in the UWB communication frequency band and radiate in the Bluetooth communication frequency band, the first antenna unit and the second antenna unit share the metal floor and the microstrip Feed line conduction strip; the first antenna unit is in the shape of a rectangle with rounded corners, the right side of the first antenna unit includes the first antenna body, the left side of the first antenna unit includes a rectangular notch, and the left side of the second antenna unit includes The second antenna body and the right side of the second antenna unit have multiple bent parts, and the multiple bent parts are arranged in the rectangular notch of the first antenna unit. The antenna provided by the invention is miniaturized to realize that the antenna with a compact structure can cover two wireless standard frequency bands.

Description

technical field [0001] Embodiments of the present invention relate to the field of printed antennas, in particular to a miniaturized UWB and Bluetooth printed antenna. Background technique [0002] Applicable to a wide range of wireless systems, Ultra Wideband (UWB) dates back to the telegraph system that included the famous transmission of transatlantic pulse signals in 1901. The technology has since found some use in radar, mainly for military purposes. In 2002, the U.S. Communications Commission passed the regulations to classify the 3.1-10.6 GHz frequency band as commercial and the 22-29GHz frequency band as vehicle radar systems. Since then, UWB technology has broken through the past few decades. In the next few years, UWB technology has become a powerful competitive solution for the realization of short-distance high-speed wireless systems due to its simple transceiver structure, low power consumption and high transmission rate, and various related applications have b...
