Embodiment 1

[0022] The first scheme adopts stripline multi-layer structure, designs 2 equal power dividers and equal phase 12 unequal power dividers 1 in one plane, and designs unequal phase 12 unequal power dividers 2 in another plane Inside, the signal transmission between the two layers is realized by metallized holes. This solution has high requirements on the processing technology of the microstrip board, and it is extremely difficult to realize the project.

Embodiment 2

[0024] In the second scheme, the 2 equal power dividers and the 12 unequal power dividers with different phase characteristics are designed separately. The connection structure realizes the signal transmission between the two, and all the devices are integrated in a feed network box seat 6. This scheme has lower requirements on the processing technology of the microstrip board, but it has a higher impact on the structural design and The processing puts forward higher requirements, and the engineering realization is relatively easy. The best embodiment of the present invention is to adopt second kind of scheme to realize.

[0025] refer to figure 2 , image 3 . In the following embodiments, a dual-beam feeding network with a size of 200×132×16.5 mm is taken as the best embodiment. Since there are many devices that make up the dual-beam feed network, the feed network body is structurally divided into four parts: equal phase 12 unequal power divider circuit board 1, unequal ...

Abstract

The invention provides a double beam integrated feed network, wherein amplitude phase error of the feed network is easy to control and the feed network is small in debugging workload, high in reliability and low in cost. The technical scheme includes that 12 routes of input signals of E1, E2...E12 are equally divided into two routes of signals through 12 2-equal power dividers. One route composes E gamma 1 through a 12-unequal power divider circuit board (1), and after phase delay is carried out, composition is carried out on the other route of the signals through a 12-unequal power divider circuit board (2), and each delay phase is composed to E gamma 2 in sequence. Physical vertical connection structures among the 12-unequal power divider circuit board (1), the 12-unequal power divider circuit board (2), the twelve 2-equal power dividers (3) and two output adaptors (4) is achieved by adopting a coaxial cable and micro-strip translation method, the 12-unequal power divider circuit board (1), the 12-unequal power divider circuit board (2), the twelve 2-equal power dividers (3) and the two output adaptors (4) are all integrated inside a feed network case seat (6).

Description

technical field [0001] The invention relates to a dual-beam integrated feed network applied to a phased array antenna. Background technique [0002] The dual-beam feeding network is widely used in the dual-beam receiving system of the phased array antenna, and forms two receiving beams with different directions at the same time, one of which points to the normal direction of the antenna array, and the other beam deviates from the normal direction of the antenna array. Usually in the dual-beam feeding network, the 2 equal power dividers and the 12 unequal power dividers are placed separately and designed separately, and the 2 equal power dividers and the 12 unequal power dividers are connected by radio frequency cables. Such a dual-beam implementation method will bring the following problems: the structural space required to place the entire feed network is large; because the cables between the 2 equal power dividers and the 12 unequal power dividers have strict phase require...
