Need complicated supply network road and higher cost.
Meet various system requirements it follows that designing, adapt to the antenna of application environment complicated and changeable, is modern
Communication continues the key of development.
In current published document, directional diagram reconstructable aerial type is included mainly reflector antenna and is opened with automatically controlled
Close the parasitic array scatterer of control.However, (1) is variable to realize by adding switch on the reflecting surface of reflector antenna
Reflected phase and adjustable beam direction.But it is less than 60 ° of scanning angle, and it is logical to cannot be satisfied broadband wireless with rapid changepl. never-ending changes and improvements
The requirement of letter；(2) using the mutual coupling between different radiating elements, intermediate main radiating antenna is posted energy coupling to surrounding
On raw unit, the varactor that is loaded in parasitic element can so that this parasitic element generates phase offset, primary antenna with
The relationship of such a phase difference between parasitic element will produce the effect of beam scanning.Although this method can reach big model
The frequency sweep angle enclosed, but the frequency range of ESPAR antennas is relatively narrow, only 15%.(3) some other designs are to be based on single armed
On the basis of helical antenna, quasi-yagi antennas either SIW electromagnetic horns, it is restructural equally to realize wave beam.But this
The antenna pattern of a little antennas is less desirable, and wave beam swept frequency range is relatively narrow and sufficiently bulky.Various aspects as described above lack
Application of these directional diagram reconstructable aerials in modern wireless communication systems will be limited by falling into.
