Abstract
The invention provides a 6-18GHz (gigahertz) ultra-wideband array antenna which comprises a plurality of dipole antennas. The dipole antennas are in close-packed array to form dipole sub-arrays, and radiation arms of the neighboring dipole sub-arrays are interlapped. Operation wideband of the arrays is widened by the aid of high coupling effect generated among overlapped radiation vibrators; in addition, in order to eliminate some changes of susceptance in array scanning, a medium wide-angle matching layer is added at the top of the high-coupling array to further counteract change of grounding reactance with frequency, the obtained dipole sub-arrays have wider frequency band characteristics, and wide-angle scanning is realized. Through coupling effect among units, operation state of the antenna is improved, antenna performance is improved, and the ultra-wideband array antenna with three times of frequency interval is realized.

Advantage.
The technical solution adopted for the present invention to solve the technical problems is：Including some dipole antennas, described dipole
Sub-antenna close-packed arrays, constitute dipole array, and the radiation arm of adjacent dipole is overlapped.
Present invention additionally comprises wide angle matching layer, positioned at radiating doublet top, further offsets ground plane reactance with frequency
Change, thus obtained dipole array has broader frequency bandwidth characteristicses, realizes large-angle scanning.
Present invention additionally comprises the antenna-reflected plate of metal, between radiating doublet and feed networking.
The invention has the beneficial effects as follows：Exist between the lap of the adjacent array element of compact arranged dipole array stronger
Mutual coupling effect, a certain amount of electromagnetic coupled is introduced between each array element of dipole array can then make antenna array have ultra broadband special
Property.The present invention improves Antenna Operation state by the coupling effect between unit, improves antenna performance, realizes the super of 3 octaves
Wide band array antenna.
