Description
Technical field
The utility model relates to a kind of communication technology, particularly relates to a kind of communication antenna.
Background technology
Antenna is a kind of converter, it is the guided wave of transmission above-the-line promotion, be transformed into the electromagnetic wave propagated in unbounded medium (normally free space), or carry out contrary conversion, be used for launching or receiving electromagnetic parts in wireless device, radio communication, broadcast, TV, radar, navigation, electronic countermeasures, remote sensing, the engineering systems such as radio astronomy, every electromagnetic wave that utilizes carrys out transmission of information, all rely on antenna to carry out work, in addition, transmitting in energy with electromagnetic wave, the energy emission of non-signal also needs antenna, general antenna all has invertibity, namely both can be used as transmitting antenna with common antenna, also can be used as reception antenna, the same antenna is identical as the fundamental characteristics parameter of launching or receive, the reciprocity theorem of Here it is antenna, symmetrical dipole is a kind of classics, most popular antenna up to now, single half-wave doublet can on the spot use separately or be used as the feed of parabolic antenna simply, also multiple half-wave doublet can be adopted to form antenna array, the oscillator that two arm lengths are equal is called symmetrical dipole, every arm lengths is quarter-wave, total length is the oscillator of 1/2nd wavelength, claim half-wave doublet.
In addition, also has a kind of special-shaped half-wave doublet, can regard as and all-wave symmetrical dipole be amounted to into a long narrow rectangle frame, and two of all-wave symmetrical dipole end points are stacked, this long narrow rectangle frame is called folded dipole, note, the length of folded dipole is also be 1/2nd wavelength, therefore be called half-wave folded dipole, the back reflection of antenna to be concerned with the principle made and add based on resonant cavity ripple, resonant cavity is by main reflector, subreflector and feed are formed, by the feed radiation directive main reflector of slow wave structure, reflected by main reflector again, again reflected to subreflector fork, so axially formed along it in resonant cavity, stationary field ", " condition in crossing site is main in formation, the integral multiple that the spacing of subreflector is, the resonant cavity formed because of backfire antenna is opening, suitable selection antenna sections size, the energy emission of opening resonant cavity can be made to free space, form sharp wave bundle, its greatest irradiation direction along it axially, because the radiation direction of this antenna is contrary with the radiation direction of feed, therefore this antenna is seen as antenna back reflection, the critical parameters affecting antenna performance have a lot, usually can adjust in Antenna Design process, as resonance frequency, impedance, gain, aperture or antenna pattern, polarization, efficiency and bandwidth etc., in addition, transmitting antenna also has maximum rated power, reception antenna then has noise reduction parameter.
The signal frequency range that current existing communication antenna receives is less, is installing and using comparatively inconvenience in process.
