Magnetic wave, or carry out opposite transformation.It is used to emit or receive the component of electromagnetic wave in wireless device.Radio communication,
The engineering systems such as broadcast, TV, radar, navigation, electronic countermeasure, remote sensing, radio astronomy, it is all to use electromagnetic waves to transmitting information
, antenna is depended on to work.In addition, the energy radiation of non-signal is also required to day in terms of transmitting energy with electromagnetic wave
Line.General antenna all has invertibity, i.e., both can be used as transmitting antenna with common antenna, it is also possible to make receiving antenna.On the same day
Line is identical as transmitting or received fundamental characteristics parameter.The development of radio technology, it is close with the development of antenna technology
It is related.Short-wave receiving antenna design now, generally uses active and passive two methods.The design of passive antenna, is usually adopted
The effective aperture of antenna is determined with the ratio of received maximum power and power density, it may be assumed that A=Pmax/S.In formula, A has for antenna
Imitate bore；Pmax is received maximum power；S is power density.The design of active antenna is compensated with the gain of active electric network
Gain caused by passive antenna becomes smaller because of size declines, to reach reduction antenna size purpose.According to traditional passive day
Line design principle, the antenna frequencies range designed can not reach higher in 30MHz---1350MHz frequency range
Radiation efficiency, and input impedance variation is very greatly.Traditional merogenesis payload antenna design method is difficult to determine optimal by calculating merely
Loading position is only determined by continuously attempting to, and needs repetition test in this way, has certain blindness, and workload is very big.
Using active antenna design principle design antenna, although frequency band can be widened, also reduce simultaneously antenna signal-to-noise ratio and can
By property, the formation probability of intermodulation product is increased, is difficult to obtain uniform input impedance.
