The optimum aperture size of battle array；In order to adapt to portable and vehicle-mounted use, antenna array structure is designed using folding storage.Receipts can be detectd
Sky wave, ground involve high elevation angle sky wave etc., and greatly improve antenna detects receipts scope.
The short antenna quantity is 5, and the long antenna amount is 4.Further, the preferred scheme new as this.
The connection antenna sets limited block, and the limited block is located above long antenna peak, is minimum positioned at short antenna
Point lower section.Further, the preferred scheme new as this.
The spacing block length is less than so the overall width of short antenna.Further, the preferred scheme new as this.
The short antenna is identical with vast of heaven line width dimensions, further, the preferred scheme new as this.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of transmission equipment contraction structure for being used to communicate of the present invention has the design advantage of wire antenna and frame antenna concurrently, adopts
The wideband operation characteristic of dipole antenna is realized with load mode；Using low noise FET and symmetrical operation mode, improve
Antenna dynamic range, antenna noise is reduced,；
2nd, a kind of transmission equipment for being used to communicate of the present invention and system Direction Finding Algorithm carry out matching optimization, determine antenna array
Optimum aperture size；In order to adapt to portable and vehicle-mounted use,；
3rd, a kind of transmission equipment for being used to communicate of the present invention, can detect receipts sky wave, ground involves high elevation angle sky wave etc., greatly
Improve antenna detects receipts scope.
