Technical scheme: wide-band shaped-beam antenna of the present invention is made up of asymmetric tapered slot antenna and rearmounted metallic reflection plate, central authorities at rearmounted metallic reflection plate have the slit, and asymmetric tapered slot antenna vertically inserts this slit and rearmounted metallic reflection plate and asymmetric tapered slot antenna are connected into electric contact state; Wherein, asymmetric tapered slot antenna is made of dielectric-slab and the metal level that is positioned at the dielectric-slab both sides, is the metal level that is provided with asymmetric tapered slot in a side of this dielectric-slab; Opposite side is the microstrip feed line layer.The slit of rearmounted metallic reflection plate is provided with the circular hole that external coaxial cable is linked to each other with the microstrip feed line of asymmetric tapered slot antenna, installs AN connector in this circular hole.
Upside tapered slot section on the metal conductor layer, the inner of downside tapered slot section are connected with circular line of rabbet joint resonant cavity respectively, are provided with the choke groove of many degree of depth gradual changes on the upper metallization layer edge on the metal conductor layer.The microstrip feed line layer is by the microstrip line section of three sections different in width promptly: little coupled section with 90 ° of knuckle sections, impedance matching section and little band-line of rabbet joint is joined in proper order and is formed.Asymmetric tapered slot antenna is made by the dielectric-slab of two-sided deposited copper,
Beneficial effect: compared with prior art, the present invention has following advantage:
The invention has the advantages that the shaped-beam that to realize on the mobile communication broadband.
The present invention adopts and the diverse scheme of traditional base station antenna figuration technology, design simultaneously meets the horizontal plane and the vertical plane directional pattern of base station antenna requirement, need not to organize battle array and the complicated array-fed network of design, can realize in the mobile communication figuration requirement to the base station antenna pattern, comprise the inhibition of secondary lobe, the filling at following zero point, and main have a down dip to appropriateness as required etc.
The present invention utilizes the tapered slot antenna structure to reach about 20% broadband character, is fit to mobile communication application.The present invention adopts print structure, makes simply, is beneficial to the batch process of antenna.
