Novel planar waveguide magic T in the system such as equipment and weapon guidance equipment.
Background technology
Waveguide magic T is a kind of power distribution passive device, because its power capacity is very big, and easy to manufacture simple in construction.
It is widely used in radar system devices, navigation system devices, microwave telecommunication devices and microwave test system.Usually do conduct
The parts such as power distribution, power combing, power adjustment, sum-difference network.
Common waveguide magic T has two shortcomings：1st, short transverse is higher, can cause the volume and weight of whole system all
Than larger；2nd, two public waveguides mouthful are orthogonal, not in approximately the same plane, are not easy to coplanar circuit integrated.In order to
Improve the above-mentioned two shortcoming of waveguide magic T, people employ a variety of new methods, develop much be based on PCB circuits first
The Planar Magic-T structure of plate, including microstrip line, strip line, SIW substrate integration wave-guides etc., these structures all realize magic T work(
Can, and it is very easy to and planar circuit is integrated, but these structures are due to being all PCB forms, it is small all to there is power capacity, inserts
Enter big shortcoming is lost.Chengdu Sai La Sadens Science and Technology Ltd. develops a kind of directrix plane waveguide magic T, using a kind of π shapes knot
Structure, is successfully realized the planarization of waveguide magic T, but the directrix plane waveguide magic T is to realize plane by various mating structures
Magic T functions, therefore, short transverse high shortcoming big there are still volume, and structure is extremely complex, and machining tolerance is difficult control
System, manufacturing cost is very high, improper large-scale production.The Chu Qing of South China Science ＆ Engineering University is clear and scientific and technological group five of China Electronics
14 Wang Pengfei etc. all develop a kind of Planar Magic-T structure of utilization probe coupled modes, the Planar Magic-T compact conformation,
It is highly low, it is easy to which that and planar circuit is integrated, but the probe location tolerance of the structure cannot ensure, cause the product of the structure into
Product rate is not high, and amplitude coincidence and phase equalization cannot also ensure.
