Penetrate plate conducting.
The principle of the present invention is as follows：
The top of radiating doublet is arranged in top load plate, by connecting column made of metal and is arranged under radiating doublet
The reflecting plate of side is connected and is connected, and realizes top load plate earthing.Connecting column can be former by top load close to the outer rim of top load plate
Reason realizes broadening bandwidth.And be to obtain better broadened bandwidth effect, several can be equipped with for adjusting radiation by pushing up in load plate
First hollow hole of performance, first hollow hole can be the shapes such as sector.In addition, top load plate, reflecting plate, baseplate part can be
It slab construction and is parallel to each other, the volume of antenna is smaller, and concealment is good.
Further to broaden bandwidth, according to gradual change principle, transducer part can constitute its cone by several round table-like oscillator blocks
Shape.The outer profile of each oscillator block is in frustum cone structure, and the upper bottom of any oscillator block and the bottom of adjacent vibration generators block are connected with each other, several
A oscillator block, which is sequentially connected, constitutes stepped transducer part；According to slow wave principle, several use can also be set on baseplate part
In the second hollow hole of adjustment radiance, which can be the shapes such as arc line shaped.
The present invention has bandwidth, antenna section are low, easily hide, can effectively cover 2G, 3G, 4G LTE-A, WIFI etc. to lead to
Believe channel, the advantages that processing cost is low, easy to produce.
