Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Taking the ultra-broadband printed monopole antenna of 5.8GHz notch as an example, the present invention is further described in detail, the antenna structure is as follows figure 1 As shown, the antenna includes: a tapered and stepped radiation unit 1 , a partial metal ground plane 2 , a dielectric substrate 3 and a microstrip feeder 4 .

[0021] On one side of the dielectric substrate 3 are the gradient stepped radiation unit 1 and the microstrip feeder 4, and the other side is a part of the metal ground plane; the radiation unit 1 is connected to the microstrip feeder 4, and an inverted L-shaped groove is etched symmetrically along the direction of the microstrip feeder 7. Open a semi-elliptical notch 5 on part of the metal ground plane 2 of the antenna, and open an L-shaped slot 6 on the side of part of the metal ground plane. As l...

Abstract

The invention discloses a super-wide band antenna with a notching characteristic. The super-wide band antenna comprises a radiating unit (1), a metal ground plane (2), a medium substrate (3) and a micro-strip feed line (4). A combination body of the radiating unit (1) and the micro-strip feed line (4) is located on the top face of the medium substrate (3). The metal ground plane (2) is located on the bottom face of the medium substrate (3). The radiating unit (1) is in a gradually varied ladder shape. According to the super-wide band antenna with the notching characteristic, the radiating unit (1) adopts a rectangle shape, frequency range of the antenna is expanded through design of the gradually varied steps, and the antenna is convenient to design and debug and can be used in a super-wide band wireless communication system. On the condition that the size of the antenna is minimized, a semi-oval notch or a ladder-shaped notch (5) of the super-wide band antenna improves bandwidth of low frequency stage of the antenna, and achieves impedance bandwidth of a super-wide band.

Description

technical field [0001] The invention relates to an antenna used in ultra-wideband Ultra-WideBand (UWB communication for short), especially an ultra-wideband antenna with notch characteristics. Background technique [0002] Ultra-wideband (UWB) technology is a new type of wireless communication technology that has received widespread attention in recent years, and its transmission signal bandwidth can be as high as several gigahertz (GHz). UWB technology can generally be divided into two basic implementations of the pulse system and the carrier system. The pulse system UWB transmits information through the baseband pulse sequence, which has the advantages of simple system structure, low cost, low power consumption, etc., and has a wide range of applications in the fields of wireless communication, ranging, detection, etc. Detection, energy detection, analog correlation detection and other methods, whose processing performance is limited by analog processing, generally can on...
