Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of aviation management array antenna radiator, comprise radome 1 and base plate 2, radome 1 and base plate 2 are connected to the obturator of hollow, obturator inside is provided with the support column 5 vertical with base plate 2, support column 5 from top to bottom interval arranges radiating element layer 3 and feeding network layer 4, and wherein radiating element layer 3 and feeding network layer 4 be arranged in parallel; Also comprise radio frequency socket 6, radio frequency socket 6 passes base plate 2 and is connected with feeding network layer 4.
Described radio frequency socket 6 be arranged in parallel with support column 5.
Described support column 5 has four, and be arranged in parallel.
Described feeding network layer 4 is provided with metal level.
Described metal level is provided with H groove part crack.
Described radiating element layer 3 is provided with metal patch.
Described metal patch is rectangle.
Antenna operation principle: by power splitter feed is carried out in H shape slit, power splitter adopts the 100W isolation resistance, does not mate the reflected energy that causes with absorption because of port Impedance, thus expansion impedance bandwidth; The merits such as power splitter are divided output, energy from microstrip line by slot-coupled to metal patch, encouraged the constant amplitude homophase, energy superposes in the radiator center and forms the high-gain wave beam.
Radiofrequency signal is coupled to the metal patch on the radiating element layer 3 by the H groove part crack on the feeding network layer 4 by radio frequency socket 6 input feeding network layers 4.Metal patch sees through respectively radome 1 outside emittance.Adopt the slit of H shape, can on the basis that ensures larger coupling amount, greatly reduce the slit area, thereby reduce the backward radiation of slot-coupled structure.
