Description
Technical field
The utility model relates to the signal antenna field, a kind of terrestrial antenna structure that is used for received television signal of saying so more specifically.
Background technology
In the transmission course of TV ground signal, in order better to avoid interference and make full use of band resource, the dual polarization technology of meeting usage level polarized signal and perpendicular polarization signal.And the ground digital television signal band limits distributes wider, the frequency range of VHF (Very high frequency) and UHF (Ultra High Frequency).Traditional Yagi antenna, logarithm periodic antenna can only receive the electromagnetic wave signal of a polarised direction, and are difficult to receive simultaneously VHF and two sections electromagnetic wave signals of UHF.
Traditional logarithm periodic antenna is done height for the gain antenna, and suitable frequency range is done wide, and it is many to be connected two oscillator quantity on the parallel metal conductor, and oscillator needs antenna size very big according to length from being short to long arrangement, causing.
What traditional dual polarized antenna generally adopted is two feed port, and a feed port transmits the signal of horizontal polarization, and another one point feed port transmits the signal of perpendicular polarization, can not a shared feed port.
There is the different frequency electromagnetic wave of different polarised directions in the TV ground signal, adopts traditional television receiving antenna, and the user is received television signal all, also just can not receive whole TV programme.The antenna user must use two antennas simultaneously for the signal that can receive horizontal polarization and the signal of perpendicular polarization; A horizontally-polarized antenna, a vertical polarized antenna.
The utility model content
The utility model technical problem to be solved is the defective that overcomes prior art; Design a antenna; Make it can receive horizontal polarized wave and vertically polarized wave simultaneously, and receive the TV signal of VHF section and UHF section simultaneously, make it aspect reception signal bigger gain and directivity arranged.
This patent is realized above-mentioned purpose through following technical scheme.
A kind of antenna structure that this patent designed; Comprise leading body, some radiating elements and feed port; Said radiating element is alternate to be installed along leading body; Said feed port is installed in the front end of leading body, and its improvement part is that said radiating element comprises horizontal radiation unit and vertical radiation unit, and the part of horizontal radiating element is alternate with the vertical radiation unit at least is installed on the leading body.The utility model makes full use of resource, on two aerial integration to antennas originally, adopts the dual polarization technology, can receive horizontal polarization signal and perpendicular polarization signal simultaneously, makes that the antenna applicable surface is wider, and structure is compact more, and it is littler to take up room.This antenna is fit to the electromagnetic area of the different polarised directions of TV signal height band transmit very much.Can at utmost utilize an antenna to receive all TV programme of these two frequency ranges.
In order further to improve the effect that signal receives, the spacing between said some horizontal radiations unit or the vertical radiation unit is by the index Design of cycle logarithm antenna.The radiating element of arranging according to the cycle logarithm can make each radiating element all be positioned at the strongest energy place that signal is propagated, and signal strength signal intensity is big like this, and reception is good.
The described leading body of the utility model comprises two linear pattern leading bodies, and horizontal radiation unit and vertical radiation unit all are installed on two linear pattern leading bodies.This structure further with two independently antenna be integrated in the antenna, help further enhancing signal intensity, improve reception.
In order to make the signal of two integrated antennas consistent, said horizontal radiation unit and vertical radiation unit are symmetrically distributed on the leading body respectively.The above two horizontal radiation unit or vertical radiation unit that is symmetrically distributed on the leading body is installed in respectively on the different linear pattern leading bodies at same position.Consistent signal helps the verification and the processing of signal, can simplify the structure that subsequent conditioning circuit is handled, and improves signal reception.
For the signal that prevents two stand-alone antennas disturbs, on the same position, be installed in the installation of on level or vertical direction, staggering of two horizontal radiation unit or vertical radiation unit on the different linear pattern leading bodies.Though radiating element staggers on level or vertical direction each other, two independently antenna remain centrosymmetric structure, promptly can be overlapping fully after any one antenna Rotate 180 ° with another one.
For the signal that is fit to various frequencies receives, extremely terminal from the front end of leading body, the length of horizontal radiation unit or vertical radiation unit progressively shortens.Can well receive for low frequency and high frequency like this.According to the polarization of electromagnetic wave situation, if high frequency is vertically polarized wave, low frequency be the radiating element horizontal positioned that horizontal polarized wave then can be long with antenna.All be to receive with long radiating element for low frequency in a word, the polarization of electromagnetic wave direction that receives as required goes to select how to install.
In this patent, said horizontal radiation unit comprises horizontal dipole and horizontal metal bar, and horizontal dipole connects leading body and horizontal metal bar; The vertical radiation unit comprises vertical dipole and vertical metal bar, and vertical dipole connects leading body and vertical metal bar.This patent is made into standard component with horizontal radiation unit and vertical radiation unit, helps the installation of structure like this, need not the professional person and also can accurately scattered parts be installed.
The leading body cross section of this patent is square, and horizontal metal bar and vertical metal bar cross section are rounded.Square structure more helps the installation of radiating element, and radiating element is divided into parallel and vertical two kinds, can be directly installed on two sides of leading body.And according to the position difference in the side of the different linear pattern leading bodies of same position, the installation of can directly staggering.
The front end of two linear pattern leading bodies of this patent and the terminal isolation fixture that two linear pattern leading body parallel interval are distributed that is respectively equipped with.The purpose of this structural design also is for the ease of installation, fixes through standard component, and the user need not to consider concrete designed distance when installing, and is very simple and convenient.
The electromagenetic wave radiation unit of this patent is made up of the metal aluminum pipe, is positioned at two orthogonal planes, is made up of the unit cross arrangement of number of metal straight conductor oscillator.The length of these metallic conductors has nothing in common with each other, and the length of metallic conductor designs according to operating frequency of antenna, forms the queueing discipline of logarithm periodic antenna.A polarised direction of antenna is designed to an antenna that is operated in high band (UHF); The another one polarised direction becomes perpendicular quadrature with above-mentioned polarised direction, is designed to an antenna that is operated in low-frequency range (VHF).Two electromagnetic waves that polarised direction received, the high-frequency signal electric current that excitation produces is exported from a feed port.Because VHF and two separate frequency ranges of UHF, disturbing can not appear in the channel filtration through TV.Thereby the antenna of above-mentioned design can receive the TV signal of two frequency ranges.The utility model is simple in structure in addition, and integrated level is high, and is easy for installation, has substantive progressive and distinguishing feature with respect to prior art.
