Description
Technical field
The present invention relates to a kind of omnidirectional antenna, more particularly to a kind of 400MHz ~ 3GHz omnidirectional antennas.
Background technology
Directional aerial（Directional antenna）Refer to transmitting and to be received on some or certain several specific directions
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 the effective rate of utilization for increasing 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, and the wave beam of one fixed width is shown as on height pattern, and generally lobe width is got over
Small, gain is bigger.Omnidirectional antenna is generally used for the site type of suburbs and counties under the jurisdiction of a large city great Qu in mobile communication system, and coverage is big.But
It is that existing omnidirectional antenna has complex structure, designs cumbersome, poor universality and have 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.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of 400MHz ~ 3GHz omnidirectional antennas, solve
The complex structure of prior art, design cumbersome, poor universality and have the problem of certain defect.
The purpose of the present invention is achieved through the following technical solutions：400MHz ~ 3GHz omnidirectional antennas, including be fixed on
Outer cover above base, is provided with epicone antenna and lower cone antenna in outer cover, pass through between described epicone antenna and lower cone antenna
Pillar be supported with it is spacing；Described base is inner concave shape base, and connection ring has been connected by screw in the interior recess of base.
Described outer cover is that surrounding is cylinder, and top is the glass steel material outer cover of arc.
Described epicone antenna is the antenna of cone and 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, epicone antenna passes through spiral shell with the top of lower cone antenna
Post is connected.
Radio frequency interface is connected with below described connection ring.
The beneficial effects of the invention are as follows：400MHz ~ 3GHz omnidirectional antennas, its lamps structure is simple, frequency coverage is wide, set
The characteristics of meter is flexible and with low cost, can adapt to outdoor severe external environment condition, with good weatherability；Antenna is in level
It is not in rip-panel that the method figure in face is more round.
Brief description of the drawings
Fig. 1 is the structure chart of antenna；
In figure, 1- epicone antennas bore antenna under 2-, 3- connecting tubes, 4- pillars, 5- connection rings, 6- bases, 7- outer covers, 8- studs,
