Abstract
Provided is a series-fed vertical antenna which comprises an antenna body, an antenna seat, and a coaxial cable. The antenna body is formed by multiple radiating units and multiple inverters which are alternately connected end to end in series. The antenna body is inserted into a metal tube on top of the antenna seat and is connected with one end of the core wire of the coaxial cable. The other end of the coaxial cable is connected with a transceiver. The bottom of the antenna seat is connected with a conductor outside the coaxial cable. The radiating units may perform electromagnetic radiation within a preset frequency range by using the inverter. The series-fed vertical antenna has advantages of high gain, high structural strength, high reliability, easy processing of the antenna body, low cost, and convenience for large-batch production.
Description
Technical field
The utility model relates to a kind of series feed upright antenna, particularly is applied to the full phase antenna of high-gain on vehicle-mounted and relay station
Background technology
Along with the development of wireless telecommunications industry, wireless telecommunications are ubiquitous, in order to increase communication context, particularly at family expenses car, communication test car etc. at a high speed, under the requirement of high-quality wireless signal, need to have high-gain and isotropic antenna is also increasingly important.To reduce cost of manufacture simultaneously, be convenient to assembling, vast domestic consumer can be accepted.
What the most car antenna adopted is sucker unipole antenna or fiberglass formula flagpole antenna, and the low and fiberglass formula flagpole antenna of sucker antenna gain is along with jolting of car easily fractures.
Summary of the invention
The purpose of this utility model is to provide a kind of series feed upright antenna, this antenna high-gain, has a high structural strength again.
To achieve the above object of the invention, the utility model is by the following technical solutions:
This series feed upright antenna, it comprises: antenna body, antenna pedestal, coaxial cable, described antenna body alternately is connected in series by a plurality of radiating elements and a plurality of gun stocks first and last and forms, antenna body is inserted on the metal tube on antenna pedestal top, antenna body is connected with coaxial cable core wire, the coaxial cable other end is connected with transceiver, and antenna pedestal bottom is connected with coaxial cable outer conductor.
Described antenna pedestal bottom and coaxial cable outer conductor connected mode be coaxial cable outer conductor bottom antenna pedestal with magnetite or metallic plate be connected.
Described radiating element is wire, metal tube or PCB.
Described gun stocks adopts inductance coil or comes and goes rolls over the shape wire again.
The quantity of described a plurality of radiating elements is 2-7, and the quantity of gun stocks is lacked one than the quantity of radiating element.
In antenna body, the equivalent length of each radiating element is 1/2 λ.
The material of described radiating element adopts wire or metal tube or PCB, and its length is 1/2 λ.Electric current singly enters into described gun stocks by radiation, because leading portion radiator length is 1/2 λ, electric current in described gun stocks is reverse, so gun stocks adopts inductance coil or come and go and roll over again shape (snakelike) structure, makes it substantially not have electromagnetic radiation.
The utility model has the advantages that: Antenna Design is simple, high-gain, high structural strength, and reliability is high, and cost is low.
