Abstract
The present invention discloses a plum blossom-shaped omnidirectional receiving antenna device for televisions, which can receive signals from television stations in any directions and with any channels. The device is similar to a growing plum blossom, forms a circular shape and is horizontally used, and the omnidirectional operation is realized. Two plum blossom petal-shaped vibrators of the device, which are transversely symmetrical, receive 1 to 5 channels, and a plum blossom petal-shaped vibrator in the longitudinal direction receives 6 to 57 channels, and all channels are realized. The longitudinal vibrator of the device is a director of the two transverse symmetrical vibrators which are also a reflector of the longitudinal vibrator, and accordingly, high gain is realized.
Description
The present invention relates to a kind of television receiving antenna device, particularly a kind of new Quincuncial omnidirectional receiving antenna for TV device belongs to the wireless aerial field.
Existing television receiving antenna mainly is made up of oscillator, director, reflector, feeder line etc., the common feature of such television receiving antenna is the problem that all has directivity, promptly when director one end pointed at television platform, reception is best, but, can not receive the signal that TV station sends in side surface direction, direction can not receive TV station's signal at the back side of the antenna that reflector is arranged.At present, TV station is more and more, and the channel of each TV station, orientation, distance have nothing in common with each other again, use existing television receiving antenna, just can not watch its side direction and station synchronization dorsad.
In order to address this problem, common way is: 1, set up the antenna of several sizes and sensing different azimuth, this has very big difficulty and inconvenient for the user; 2, use the motor steering antenna, but because motor is in outdoor easy damage, must often turn to during TV reception and pretty troublesome, the frequency acceptance band of adding an antenna is limited, therefore uses also undesirable.
The present invention adopts and has the diverse method of television receiving antenna now to overcome the existing defective of above-mentioned antenna.
The purpose of this invention is to provide a kind of new Quincuncial omnidirectional receiving antenna for TV, use this antenna both need not turn to, again can each orientation of fine reception and the TV signal of each channel.
In order to achieve this end, the technical solution adopted in the present invention is as follows:
A kind of antenna of being made up of oscillator, upper supporting plate, lower carrier plate, insulation cushion, feeder line and stay pipe is characterized in that:
This antenna has eight oscillators that identical plum is petal, these oscillators respectively level be installed in equably garden shape upper supporting plate and garden shape lower carrier plate around, shape resembles a plum blossom in full bloom.Be garden shape, to realize comprehensive reception, receive the TV signal of 1 to 5 channel with the oscillator of horizontal two symmetries, receive the TV signal of 6 to 57 channels with a vertical oscillator, to realize that all-channel receives, a vertical director that oscillator is horizontal two symmetrical dipoles, the oscillator of horizontal two symmetries is again the reflector of a vertical oscillator, to realize high-gain.The materials length of oscillator is 0.75m to 2m.
Garden shape upper supporting plate and garden shape lower carrier plate are arranged in parallel, and perpendicular to same axis.
Be provided with insulation cushion between upper supporting plate and lower carrier plate, in the middle of this insulation cushion a step Da Yuan hole arranged, be used for installing stay pipe, insulation cushion makes upper supporting plate, lower carrier plate, stay pipe all be in state of insulation each other.
The television receiving antenna of quincuncial comprehensive a, all-channel, high-gain so far, has been described.
Antenna assembly of the present invention simple in structure, easy to use, gaining is 3-5db, impedance approximates 75 Ω.
Watching of this antenna is respond well, is exemplified below:
1, in the Nangong City, need not turn to the program that just can receive 15 TV stations with the oscillator of 1.5m, wherein 8 TV stations watch respond well.
2, at Shijiazhuang City, be placed on antenna of the present invention (oscillator 1.1m) and shared antenna upstairs same, its aspect ratio common antenna is low, common antenna can only be watched 4 station synchronizations, and antenna of the present invention need not turn to and just can watch 8 station synchronizations, the program of 5 TV stations watches that effect is better, and other watches that with shared antenna effect is identical.
Below in conjunction with accompanying drawing antenna of the present invention is described in further detail.
