Description
Technical field
The utility model is related to a kind of omnidirectional antenna, more particularly to a kind of 400MHz ~ 3GHz omnidirectional antennas.
Background technology
Directional aerial（Directional antenna）Refer on some or certain several specific directions transmitting and receive
Electromagnetic wave is especially strong, and it is then zero or a kind of minimum antenna to launch in other directions and receive electromagnetic wave.Using orientation
The purpose of transmitting antenna is to increase the effective rate of utilization of radiant power, increases confidentiality；Using the main mesh of directional receiving antenna
Be enhancing signal intensity increase antijamming capability.
Due to the fast development of radio communication field, directional aerial can not meet present demand；So, omnidirectional
Antenna is increasingly valued by people；Omnidirectional antenna, i.e., show as 360 ° of all homogeneous radiations in the horizontal direction on figure, that is,
Usually described is non-directional, the wave beam of one fixed width is shown as on height pattern, generally lobe width is got over
Small, gain is bigger.Omnidirectional antenna is generally used for suburbs and counties under the jurisdiction of a large city great Qu site type in mobile communication system, and coverage is big.But
It is that existing omnidirectional antenna has complex structure, designs cumbersome, poor universality and has certain defect；So, miniaturization, knot
Structure is simple, frequency coverage is wide, flexible design and broadband omni-directional antenna with low cost are very necessary.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art there is provided a kind of 400MHz ~ 3GHz omnidirectional antennas, is solved
The complex structure of prior art of having determined, the problem of design cumbersome, poor universality and have certain defect.
The purpose of this utility model is achieved through the following technical solutions：400MHz ~ 3GHz omnidirectional antennas, including it is solid
It is scheduled in the outer cover above base, outer cover and is provided with epicone antenna and lower cone antenna, between described epicone antenna and lower cone antenna
By pillar be supported with it is spacing；Described base is inner concave shape base, and company has been connected by screw in the interior recess of base
Connect ring.
Described outer cover is that surrounding is cylinder, and top is the glass steel material outer cover of arc.
Described epicone antenna is cone and the antenna of cylindrical assembly shape.
Described lower cone antenna includes conical end and connecting tube, and described connecting tube upper end passes through screw and conical end
Connection, lower end is connected by screw with base.
Cushion block is additionally provided between described epicone antenna and lower cone antenna, the top of epicone antenna and lower cone antenna passes through spiral shell
Post is connected.
Radio frequency interface is connected with below described connection ring.
The beneficial effects of the utility model are：400MHz ~ 3GHz omnidirectional antennas, its lamps structure is simple, frequency coverage
Extensively, flexible design and it is with low cost the characteristics of, outdoor severe external environment condition is can adapt to, with good weatherability；Antenna
More round in the method figure of horizontal plane is not in rip-panel.
