Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Mainly by feed port reflection coefficient that S11(S11 is antenna) parameter judges the property of antenna
Energy.
As Figure 1-Figure 11, a kind of cone of falling disk ultra-wideband antenna, including ground connection annulus 1, ground circle 2 and conical cap 3；Institute
Stating conical cap 3 to swing to and be arranged on ground circle 2, the conical surface undulate of conical cap 3, ground connection annulus 1 is supported by earthing rod 4
On the circle of ground, the radius of earthing rod 4 is 4mm, the internal diameter of ground connection annulus 1 more than the external diameter of conical cap 3 bottom surface, ground connection annulus 1 with
The bottom surface of conical cap 3 is in the same plane.
The bottom surface radius of described conical cap 3 is 400mm, and the radius of ground circle 1 is 750mm.
Outer radius R1 of described ground connection annulus 1 is 675mm, and inside radius R2 is 490mm, can be seen that at R1 from Fig. 8 and Fig. 9 and is
When 675mm, R2 are 490mm, the better performances of antenna.
Described earthing rod 4 is perpendicular to ground and justifies 2, and the center of circle of 2 is justified on the earthing rod 4 upright projection on ground circle 2 and ground
Distance R3 is 596mm, and earthing rod 4 radius r is 16mm, by Figure 10 and Figure 11 can be seen that R3 be 596mm, r be 16mm time antenna
Better performances；Being additionally provided with short circuit post 5 between conical cap 3 and ground circle 2, its radius is 4mm, and the distance of its distance Z axis is
368mm`。
Described ground connection annulus 1 surface is 300mm to the vertical dimension between the circular bottom surface of ground.
The material of described ground connection annulus 1, ground circle 2, conical cap 3 and earthing rod 4 is copper.
The waveform conical surface of conical cap 3 is sequentially connected with by some elliptic arcs and forms, and adjacent ellipse is curved on the contrary.
The elliptic arc of the waveform conical surface of conical cap has 13 sections, the antenna when that elliptic arc being 13 as can be seen from Figure 7
S11 performance best, it is thus determined that elliptic arc is 13 sections.
The present invention is by using how the ellipse antennas of falling cap are as the pyramidal portion of discone antenna and in circular cone end face metal-loaded
Plane and short circuit post realize ultra-wideband antenna and vertical polarization.And antenna height only has 30cm, cuing open of radiant body part
Face is little, and radius is 40cm, and overall dimension is little, and the bandwidth of covering is big (90MHz-600MHz).
