Abstract
The utility model discloses an UWB (Ultra Wide Band) printed monopole antenna that can be applied to a wireless communication system. The UWB printed monopole antenna is composed of a medium substrate, a radiation paste, a micro-strip feeder and a ground face. The radiation paste and the micro-strip feeder are connected with each other and are printed on two sides of the medium substrate respectively. A rectangular groove is engraved above the center of the grounding face. The UWB printed monopole antenna provided by the utility model is adjustable in working bandwidth, good in passband matching performance, small in size and simple and convenient to manufacture.
Description
Technical field
The utility model belongs to field of antenna, relates in particular to a kind of small-sized ultra-wideband printed monopole aerial.
Background technology
Since on January 14th, 2002, FCC incorporates the 3.1-10.6GHz frequency range for after the civilian ultra broadband frequency range of exempting from licence into, the ultra broadband short-range communication technique just becomes the focus of wireless communication field keen competition, also becomes in recent years the heat subject of scientific and technical personnel's research as the ultra-wideband antenna of its important component part.
The utility model content
The utility model ultra-wideband antenna adopts the round rectangle radiation patch, opens rectangular channel and can reach the purpose of optimizing impedance bandwidth on ground plane,, by regulating the size of rectangular channel, also can regulate the characteristic impedance of microstrip line, thereby reach the purpose of widening frequency band.
The utility model adopts following technical scheme:
The utility model ultra-wideband antenna comprises medium substrate, radiation patch, microstrip feed line, ground plane, it is characterized in that: described medium substrate front is printed with radiation patch and microstrip feed line, described microstrip feed line is connected with radiation patch, described medium substrate back up has ground plane, and has rectangular channel.Wherein radiation patch is round rectangle, is positioned at the top of medium substrate; Rectangular channel is engraved in the top of medium substrate back-side ground plane, and under microstrip feed line.
The utility model compared with prior art, has following remarkable advantage:
1, pass band width is adjustable: the utility model adopts the round rectangle paster, is convenient to design and regulates, and, by changing radius of a circle and rectangle length and width, can regulate the bandwidth of operation of ultra-wideband antenna.
2, volume is little: the utility model is simple in structure, and is easy to make, and volume is little.
