Realizing method of stacked coaxial rotating hinges for broadband

Abstract

The invention relates to a realizing method for stacked coaxial rotating hinges for broadband. The method is mainly used for solving the problem that rotating hinges with higher frequency, wider broadband and more passages are required by the conventional radar. The invention belongs to the technical field of radar antennas and microwaves. The space size of a coaxial rotating hinge cavity which consists of an upper cavity and a lower cavity is small, the lower cavity and a sleeve are integrated into a whole, and an input signal is divided into two paths at an input coaxial line port. When the upper cavity rotates, the lower cavity, the sleeve and a transmission ring are relatively still together, transmission band ports for transmitting the two paths of input signals are respectively in contact type slide fit with the transmission ring in at the position of 0 degree and the relative position of 180 degrees of the lower part of the transmission ring, the transmission band ports for transmitting the two paths of input signals are respectively welded to the transmission ring in the position of 0 degree and the relative position of 180 degrees of the lower part of the transmission ring, the two paths of input signals are combined into the output signal at the output coaxial line port, and a set of reeds with convex ports are wound into one circle between the upper cavity and the lower cavity of the coaxial rotating hinge so as to realize the contact type slide fit.

Description

technical field [0001] The invention relates to a realization method of a broadband stackable coaxial rotary hinge, which is suitable for electronic equipment such as modern radars. The invention belongs to the field of radar antenna and microwave technology. Background technique [0002] The rotating part of the rotary hinge inputs the radar signal, while the relatively stationary part of the rotary hinge outputs the radar signal. The relative movement between the radar antenna and the transmitter and receiver needs to be completed by the rotary hinge. With the expansion of the radar function, the The requirements for rotary hinges are also getting higher and higher, with high operating frequency, wide frequency band, and large number of integrated channels. At present, a high-frequency choke groove structure is designed between the rotating part and the relatively static part of the rotary hinge. The structure between the rotating part and the relatively static part is di...
