The radius of place circle is 28mm, and the thickness of the first radiation item and the second radiation item is 6mm, and radiation item top is away from base bottom
Distance be 74mm.
Further, it is fixedly connected between a pair of balanced support arms on each direction by U-shaped card seat, and it is U-shaped
Deck is made up of dielectric constant of 2.25 polytetrafluoroethylene (PTFE).
The advantage of the invention is that：
(1) compared with prior art, because each radiating element of dual-polarization broadband antenna low-frequency vibrator has one second
Radiation item and two the first radiation items for being symmetricly set in the second radiation item both sides, and adjacent first spoke of the first radiation item
The angle penetrated between portion is 90 °, the line centered on balanced support arm, and the distance between two second irradiation units being oppositely arranged are
123mm, after electromagnetic wave to be imported to the radiating element by feed line, first radiation item and the second radiation item can be more
The electromagenetic wave radiation is opened well, to occupy bigger broadband, so that the work of whole band dual polarization low-frequency vibrator
Bandwidth is expanded, and is particularly suitable for use in 690~960MHZ frequency range；While radiance is realized, spoke is strengthened
The structural strength of bar and balanced support arm is penetrated, the reliability of oscillator is improved, makes the electrical property consistency and stability of oscillator
Get a promotion.
(2) dual-polarization broadband antenna low-frequency vibrator of the present invention, wherein, connect between balanced support arm by the way that U-shaped card seat is fixed
Connect, and U-shape structure deck, from the polytetrafluoroethylene (PTFE) that dielectric constant is 2.25, it acts on the echo for being to adjust oscillator unit and damaged
Consumption, extends its bandwidth of operation, adjusts polarization isolation.
