Connection, reflection oscillator is fixed on the front of H type oscillators by reflecting oscillator support column.As Figure 3-Figure 4, H types oscillator includes
Two single armeds, single armed designs λ using half-wave dipole:(300/fH) * 0.5, two single armed half-wave dipoles are L1, L2 respectively.Two
Spacing uses formula between single armed oscillator：λ:(300/fH) * 0.25, two element spacings are L3, L4 respectively.Oscillator eminence is about adopted
Use formula λ:(300/fH) * 0.3 oscillator eminence is L5.The preliminary performance indications of H type oscillators can be designed substantially according to above formula,
By careful optimization in the case of areflexia is paraboloidal, more satisfactory electrical performance indexes are debugged.
The H types oscillator set, feed protective case, feed mobile jib, cable, joint, reflection oscillator and reflection oscillator support
Post is assembled into feed irradiator and shaken (such as Fig. 1).H1 is oscillator distributing point, and face feed point spacing and length can be changed during debugging standing-wave ratio
To realize in better performance.Further analysis, the increase reflection oscillator G8 before H type oscillators, reflection oscillator size is through toning
Examination draws size long 92mm, wide in 30mm.Increase by two reflection oscillator support columns 7 (such as Fig. 2) on oscillator both sides, reflection can be allowed to shake
Son can be fixed on before H type oscillators, H types oscillator and reflection element spacing, take high frequency value to be more than half-wave long value, according to actual debugging
It is defined.
By the good feed of design and assembly, (parabola design public affairs formula can be combined with any one paraboloid 8：χ
2+ γ 2=4fZ+4f2).For convenient test, I uses square parabola 0.6*0.9 meters of existing grid, is irradiated as feed
Device oscillator reflecting surface, paraboloid is fixed on one end of feed mobile jib.After reflecting surface and source feedback composition, required according to formula
Focal length move to it is desired away from, test when can focus on request (such as Fig. 5).
1. it is as follows that the utility model is assembled into product actual test result：Method of testing uses far field 2D Pattern measurements
System, actual test, 1710~2500MHZ of test frequency range detection E faces and H faces directional diagram, gain, front and rear ratio are carried out to this product
