Embodiment 1
[0018] to combine figure 1 and figure 2 , four slot antennas 5 form a radiation unit, the main feeder cable 14 directly feeds the feed network 16 through the lower fixed base plate 2, and the feed network 16 feeds the four slot antennas 5 respectively through four feed cables 17 Electricity. The slot antenna 5 is composed of an upper radiator 15 and a lower radiator 10, and the upper reflector 7 and the lower reflector 6 form a biconical shaped reflector, and the slot antenna 5 and the biconical shaped reflector are composed of a thinner It is made of copper foil, and the cone angle of the double-cone shaped reflector is between 15° and 60°, and the height of the cone and the cone angle of the double-cone shaped reflector can be adjusted. The upper and lower radiators are installed on the PTFE support plate 11 and fixed on the medium pipe 18 through the support cylinder 9 . The slot antenna 5 of the present invention consists of a modified Vivaldi antenna. The wave emitte...
Embodiment 2
[0022] like figure 2 As shown, another embodiment of the present invention is to improve the radiation characteristics of the horizontal plane of the antenna without changing other components, that is, to change the uniformity of the radiation of the horizontal plane of the antenna. slot antenna. The slot antenna is fed to the slot antenna 5 by a feed cable 17, wherein 19 is a parasitic unit, and the parasitic unit is not directly connected to the feed cable. The antenna designed in this way can not only change the radiation uniformity (out-of-roundness) of the horizontal plane of the antenna, but also guide the propagation of electromagnetic waves to increase the flow path of current, so that it is easier to achieve good impedance matching.
