Abstract
The full-channel non-all metal antenna for TV is a receiving antenna made of plastic tube, hard paper tube or cloth tube and filled with conducting liquid or gas. The whole antenna is positioned in a plane and comprises a pair of high-frequency vibrators, a pair of middle-frequency vibrators, a pair of low-frequency vibrators, a director and the like, wherein the middle-low frequency vibrators are positioned above the high-frequency vibrators, the director which is arranged in series is arranged below the high-frequency vibrators, and the middle part and the low-frequency vibrators are arranged in parallel and fixed on a cross arm which is vertical to the high-frequency vibrators through the middle part.
Description
The present invention is the reception antenna that a kind of TV is used.
At present, the exterior aerial that TV is used, great majority are to make with aluminium or other metal materials.Therefore, need to use a large amount of nonferrous materialss, in recent years, someone has studied a kind of plastic antennas and has replaced metal antenna, to save non-ferrous metal, U.S. Pat has proposed a kind of plastic antennas No. 3961332, and it puts into a spiral hardware in the inside of plastic tube, then from this element output.This structure manufacturing process complexity, and the spirality electric conductor uses metal material also more.
The purpose of this invention is to provide a kind of function admirable, simple in structure, handling ease, with low cost, and the few nonmetallic materials reception antenna of metal consumption.
The present invention is achieved in that
Be illustrated below in conjunction with accompanying drawing:
Fig. 1 is the structure chart of this antenna
Fig. 2 is the sectional drawing of oscillator and director
It by one pair of high frequency oscillator (1), one pair of medium and low frequency oscillator (2), guide device (3) and cross-arm (4) etc. into and form, whole antenna is in the plane. The medium and low frequency oscillator is positioned at high frequency oscillator top, and the below of high frequency oscillator is the device of guiding into of arranged in series. The three is arranged in parallel and is fixed on the with it vertical cross-arm (4) by the middle part; Between medium and low frequency oscillator and the high frequency oscillator at a distance of S1=6～20cm, the two at feedback point place by lead (5) parallel connection, between feedback point a, the b at a distance of being 1.5cm～5cm, the output of antenna in, feedback point c, the d of low frequency oscillator. Guide device into and have 9～15, the distance between each is S2=4～20cm. Two kinds of oscillators and the length of guiding device into should satisfy: in, low frequency oscillator L1Be 70～100cm, high frequency oscillator L2Be 10～40cm, guide device L into3Be 10～40cm. They all are equipped with the nonmetal of conducting liquid or gaseous conductor by inside The material pipe is sealed to form, and conducting liquid can be aqueous slkali, salt solution or the aqueous solution that contains impurity. Also can adopt at the interior top layer of nonmetallic materials pipe edge layer of metal paper tinsel film, form such as silver foil, aluminium foil, Copper Foil. Lead-out wire is drawn in gaseous conductor or the metal foil film from these conducting liquids. Said nonmetallic materials refer to the hard pipe of engineering plastics, papery or cloth matter. The section configuration of pipe can be circular, square, triangle or ellipse. Circular pipe external diameter φ=2～3cm. The outer floor height L=1～2cm of rectangular tube section, wide S is 1.5～3cm.
The antenna of this kind structure, except having the advantage of greatly saving metal material, owing to adopt the scheme of in non-metallic pipe, injecting conducting liquid or gaseous conductor or edge dress metal foil film, thereby overcome plating on plastics and easily produced the problem that comes off, and greatly saved metal and also simplified technology. In addition, because the ratio of this antenna overall structure, size is reasonable, so receptivity is fine, and its passband is very wide, can from 1 to 56 wave band. Gain is high, and test result: under the distance of distance transmitting station 60km, the gain of U wave band is greater than 10 decibels, and V-band is 10 decibels, and S-band is 7～8 decibels, facts have proved, 15 channel images of this antenna reception are all very clear. Directionality is little, and different regions all can be used. This kind antenna cost is low, only has 1/3rd of metal antenna.
